About This Manual:This Manual is divided into three sections –General Information, Yakuza board specific information, andTengu specific information. The Yakuza USB Board enables you to adjust settings the old fashioned way– using the trigger and power switch. We know a lot of folks are excited about the USB programmingcapabilities but there is always the chance that you want to put on some retro Velcro sneakers and do itold school. Well – that and if you decide to adjust something at the field and don’t have a laptop withyou these instructions will show you what you need to do.The last section brings on the new hot sauce known as Tengu. Bottom line you can load Tengu on yourcomputer, plug in a USB cable to your board and by hitting a couple dropdown menus change everysetting, upload preconfigured custom settings, or even change the boot screen!As with every Mangled Manual we try to put in the notes or details that people are asking about on themessage boards. If it is in the stickies it is probably in here.

RecommendationsSettingsThe Yakuza series ship with default settings which are tuned for a wide range of trigger adjustments andgeneral usage. Obviously certain tournament series allow alternate fire modes with specificcharacteristics. The following is a list of settings which will give you a baseline. Ultimately, every markeris unique, and may require different settings for optimal performance.Semi­only tournaments: Use the default settings, possibly only changing debounce, AMB, and CPF tosuit your personal trigger adjustments.PSP: Use the PSP ramping or PSP burst fire modes, with maximum rate of fire set to the required cap forthe league (for 2009 this should be either 10 or 12 bps, depending on your division). Make suredebounce is near default values. The PSP/Millennium semi shots setting should be at 3, and thePSP/Millennium reset time should be 1000ms or less.Millennium: For 2008 the Millennium series modified their rules slightly. It should be a 12 bps cap witha 6 pulls per second activation, and requires the 1‐2‐3 semi‐auto shots like PSP mode before rampingcan begin, meaning the PSP/Millennium semi shots setting should be at 3. The PSP/Millennium resettime is not specified in the Millennium rules, but it is recommended that you keep this below 1000 ms.Many European tournaments besides the Millennium series utilize semi‐automatic, but capped at 15bps. Select the capped semi‐automatic fire mode for these events.

Yakuza Series Design & DevelopmentOn the software level, running an LCD or OLED display is relatively easy, assuming you don't have tofire a paintball gun. This represents a significant challenge.So on top of making everything fit in the marker, we also have to display information on the screen thatis intuitive, legible, and updates correctly as a player uses the board. It's one thing to turn an LED on oroff with a single instruction that executes in 0.00000025 seconds. Displaying two full lines of text acrossa 96x16 pixel display can take over 10 milliseconds, which is 1/100th of a second. Anyone who playspaintball knows that this kind of delay can cause a trigger pull to be missed, as the most commondefault debounce on any board is typically 10 milliseconds.Despite the cool visuals and extremely easy‐to‐use interface, the Yakuza software doesn't give upeven one processor cycle to make it look pretty. It never sacrifices firing performance for visuals. Whenyou need to fire that string of paint at 12.0 bps on the break of the PSP finals, any inconsistency thatoccurs will not be caused by the Yakuza software.Yakuza uses all new hardware, too. The USB Yakuza board is a step forward in technology, not just theaddition of a USB socket. PIC18 USB series microcontrollers, Texas Instruments voltage regulators andboosters, Panasonic capacitors, International Rectifier MOSFETs, and Omron microswitches addrobustness and reliability to the circuit board, and reduce the fragility of the electronics powering yourfavorite paintball marker.Features include a fine rate of fire adjustment, allowing you to tune your maximum rate of fire in 0.1 bpsincrements. Want your gun to shoot 11.9 bps? No problem. Another feature of the software is theanti‐breech bounce code, which dynamically adjusts the cyclic rate when a loader starts to run low onpaint. This helps prevent chops when a fast loader actually throws a paintball down into the breech andit bounces up, since there are no paintballs stacked above it. As many users have requested, there isalso a ramping percentage setting, adjustable from 10% to 500%, so you can tune any of the ramp basedfire modes. Lastly, there are 5 setting profiles, which allow you to save your favorite settings and loadthem later with just a few button presses, making it infinitely easier to switch between tournamentmarker rules.Altogether, Yakuza gives you the fastest, easiest‐to‐use, and most reliable circuit board available.Why OLED?When compared to an LCD, OLED screens have several advantages, including better durability, lowerpower consumption, and higher contrast, especially in sunlight.Unlike an LCD, each pixel of an OLED is a light emitting diode, and therefore emits its own light. Thismakes the power consumption directly proportional to how many pixels are lit. With an LCD none ofthe pixels light up on their own, so a backlight must be used, which drastically increases powerconsumption by lighting up the entire display instead of only the pixels that are active. Paintball

markers that use LCDs were (and still are) very difficult to read when viewed in the sun, and impossibleto read at night without a backlight.Board Installation1. Remove the currently installed grips to expose the circuitboard.2. Disconnect the wiring harness from the circuit board bygripping the plug itself – Pulling the wires may yank themout of the plug – something that generally makes themarker inoperative and will delay you getting to fire up theYakuza. Take a look at the plug and you will see the holesare off center.3. Remove the screws and lift the circuit board out of theframe. If you use a spring to return the trigger, make sure to keep track of it and the returnspring bracket.4. Place the Yakuza USB board into the grip frame and adjust the wiring if necessary to get theboard into the frame.5. Partially tighten the circuit board retention screws andconnect a battery to the board. The positive terminal istowards the front of the frame, as shown by the + and –marks on the surface of the board.6. Do a test fit to make sure the display shows properly in thegrip frame window.7. Plug the wires in making sure that the off center holes fromstep #2 match the off center wires in the circuit board.8. Install grip panels with the included screws. Using longerscrews may damage internal components of the gun and will definitely void the warranty.Care and cleaningYour Yakuza series board includes a conformal coating to help protect against damage caused bymoisture from things such as broken paint or rain. Under normal conditions, the board should continueto operate fine with small amounts of moisture present. However, paint is slightly corrosive and candestroy the conformal coating over time. In the event that you get broken paint or water on theelectronics, unplug the battery, and then use rubbing alcohol and a blast of compressed air to clean theboard off. The compressed air will ensure that everything is cleaned out from beneath the componentsand connectors.BatteriesTadao Technologies recommends the use of quality alkaline batteries such as those made by Duracelland Energizer. Photo lithium 9 volt batteries are also adequate. Batteries labeled as “heavy duty” or“super heavy duty” are not true alkaline, and will cause inconsistent operation, or may not properly

power the electronics. Rechargeable batteries are also not recommended because they typically do notprovide enough current.Trigger adjustment and switch lifeThe trigger switch used on the Yakuza series boards is a high quality tactile lever switch made by Omron.It has a life expectancy of several million actuations. The life of a trigger switch on a paintball markercan be substantially shortened by using too short of a trigger pull. It is imperative that there is at least atiny amount of travel before and after the actuation point. It is also extremely important that some kindof trigger return force is used, such as a spring or magnet. Excessive bounce may occur if a spring ormagnet is not used, or the actuation point is too close to the beginning or end of the trigger pull.Yakuza Series USB Board OperationTurn on the board by pushing the power switch. The OLED display will show the boot screen, followedby the main screen with the current fire mode, rate of fire, battery, and eye status visible.Turn off the board by pressing and holding the power switch for at least 1 second. The OLED display willturn off to indicate the board has shut down.The eye system is toggled on and off by quickly pressing and releasing the power switch. The OLEDdisplay will reflect the eye status.The use of the 4C eye system allows for much faster rates of fire because it can anticipate the nextpaintball being loaded into the breech and start the firing cycle early, which negates the delay timefound in the pneumatics of the paintball marker. The Yakuza software was written specifically to takeadvantage of this arrangement, and automatically uses the top eye set when the loader is feeding fastenough. It can also determine when the top eye set is blocked by paint or debris, and will default tousing only the bottom eye until the top is clear again. Once the top eye is clear, it will resume use ofboth eye sets.If used, the eye system cycles the marker as fast as possible. During each shot the eyes watch for thebolt to return, ending the current firing cycle and starting another as quickly as the pneumatics allow. Ifthe eye system is continually blocked (e.g. putting your finger in front of the eyes) and is unable to seethe bolt return after every shot, the max rate of fire will be reduced to about 12 balls per second toprevent further chopping, and the OLED display will display an eye malfunction. Firing the marker withpaint and air will utilize the eye system correctly, maximizing the rate of fire.The programming menu system is activated by holding down the trigger while pressing the powerswitch. The OLED display will show “Menu system initiated….” Further details regarding the menusystem can be found below.If selected in the menu system, the game timer will replace the current rate of fire indicator on the OLEDdisplay. The game timer will start after the first trigger pull.

OLED DIAGRAMSThe OLED display built into the Yakuza series board shows the user a multitude of information via textand icons. The software is written with performance in mind, and will not update the screen until theuser stops shooting for just a fraction of a second. This ensures that the screen does not interfere withthe timings of the marker.The battery indicator shows battery life by displaying a bar within the icon. The longer the bar, thehigher the battery level. A low battery is reached at approximately 7.5 volts, but if quality alkalinebatteries are used, the remaining power should be adequate for at least one more case of paint.The eye indicator is displayed as a circular icon with a number beside it. The number represents thecurrent number of eyes in use, and will display 4 if using the 4C eye system, 2 if using the stock eyes,and nothing when the eyes are off. If the top eye set becomes dirty or inoperable while using the 4Ceye system, it will also display 2 and switch to using just the bottom set.If any eyes are off or malfunctioning it will be shown in the circular indicator. If using 4 eyes, the top halfof the circle will be blocked when the top set of eyes are blocked, and the bottom half of the circle whenthe bottom eyes are blocked. If the eye system is off, the indicator displays “off.” If the eye system hasa malfunction from not seeing the bolt return, it will show an X.2 or 4 eyes, empty breech: 2 or 4 eyes, blocked breech: 4 eyes, top eye blocked:4 eyes, bottom eye blocked: Bolt not seen returning: Eyes off:MENU SYSTEMThe Yakuza menu system allows the user to quickly and easily change a multitude of settings. The textbased menu is much faster and easier to understand than LED based programming modes.To boot into the menu system the user must hold down the trigger while pressing the power switch toturn the board on. After the menu boot message, the displayed setting will be the last one that wasmodified. If this is the first time the board has been booted into the menu system, it will show the firemode.Scrolling through the settings is done by pulling and releasing the trigger. The menu will wrap around tothe beginning when the last setting is reached. You can scroll backwards through the settings by holdingdown the trigger, then pressing the power switch. Once the first setting is reached it will wrap aroundto the last setting.To change a setting the user must quickly press and release the power switch. The OLED screen willreflect this by displaying “set” in front of the current value. The setting can be modified at this point bypulling and releasing the trigger, which will advance the current value. Once you reach its maximum or

last value, it will loop back to the lowest value. You can also decrement the value by holding down thetrigger and pressing the power switch repeatedly. After the desired value is displayed, you can save thesetting by pressing the power switch. The “set” designation next to the value will disappear.Example of changing the maximum rate of fire from 12 to 20:1. Boot into programming mode by holding the trigger while pressing the power switch.2. The first setting is fire mode. Pull the trigger one time to advance to max rate of fire.3. Press and release the power button quickly. The “set” designation will display next to thecurrent value.4. Pull and release the trigger 8 times to increment the value from 12 to 20.5. Press and release the power button quickly. The OLED screen will remove the “set” designationfrom view and save the setting.6. Cycle through additional settings using the trigger, or exit programming mode by holding thepower switch for 1 second, until the OLED screen turns off.Tournament lock: The tournament lock prevents access to the menu system while enabled. It can betoggled on and off while the board is powered up in the main firing mode (not the menu system) byholding the lock switch on the surface of the board for 2 seconds. The OLED screen will display thestatus as it changes.SettingsFire mode (default semi­automatic unlimited)1. Semi‐automatic unlimited2. Semi‐automatic adjustable3. PSP ramping – 123 shots semi, on 4 th shot ramps at 5 pulls per second, resets after 1 second4. PSP burst – 123 shots semi, on 4 th shot fires 3‐round burst, resets after 1 second5. NXL full‐automatic – 123 shots semi, on 4 th shot fires full‐automatic, resets after 1 second6. Millennium ramping – 123 shots semi, on 4 th shot ramps at 6 pulls per second, ignores rampstart setting if less than 6 pulls per second7. Custom ramping – user adjustable ramping, select custom ramp start and ramp percentage8. Auto response – fires on each pull and release9. Burst – 3‐round burst10. Full‐automatic – 1 shot semi, on 2 nd shot fires full‐automatic, resets after 1 secondMaximum rate of fire (default 12 bps, range 5­30 and infinity):The semi‐automatic unlimited fire mode ignores this value, making it easy to switch back and forthbetween semi‐automatic and PSP gun rules without modifying more than one setting. Adjustable from5 to 30, with an unlimited option designated by the infinity symbol.Fine rate of fire timing (default 0.0, range 0.0 to 0.9 additional bps):Fine adjustment of the max rate of fire in 0.1 bps increments, from 0.0 to 0.9 additional bps.

Game timer (default off, range 1­60 minutes):Enables and sets the game timer, which replaces the rate of fire indicator on the OLED display whenturned on. The game timer is adjustable from 1 to 60 minutes.Debounce (default 5 ms, range 0.5­25.0 ms):The amount of time the trigger must be released for the microcontroller to allow the next trigger pull.Asynchronous interrupt based scan up to 12 million times per second that is run independently fromcode execution. Higher values reduce bounce.Anti­mechanical bounce (default 1, range 1­4):Helps eliminate mechanical bounce which can cause a loosely held paintball marker to go full‐auto.Cycle percentage filter (default 2, range 1­10):Secondary debounce filter which adjusts how far through the firing cycle that additional buffered shotsare allowed. A setting of 1 turns this filter off, while settings 2 through 10 set the percentage of thecycle that must pass before shots may be buffered. Higher settings will reduce bounce.Dwell (default 6 ms, range 0.5­25.0 ms):The amount of time the solenoid is energized during each firing cycle. Lower is less consistent, higher isless efficient.Anti­bolt stick (default off, range 1­10 ms):Bolt stick can occur when the o‐rings in the bolt settle or stick, causing the next shot to have lowervelocity. If the marker is left sitting for more than 20 seconds, ABS adds extra dwell to ensure the nextshot has proper velocity. The default is off.BIP delay (default 1, range 1­10 ms):A slight delay that allows each paintball to settle in the breech before firing.Bolt delay (default 14, range 1­15 ms):A delay that gives the bolt enough time to block the eyes on the forward stroke. Too low will causeblank or skipped shots. Too high can slow the marker down.Eye mode (default forced):1. Forced with force shot – marker only fires when a paintball is present, unless a force shot isinitiated by holding down the trigger for ½ second.2. Delayed – the eyes will watch for a paintball for up to 500 ms after each pull, then fire. This isuseful for sound activated loaders and was the stock setting on original Intimidators.Ramping start (default 6, range 4­14 pulls per second):How fast you pull for the ramping fire modes to start adding additional shots. Ramping modes only.Millennium mode will ignore settings below 6 pulls per second, automatically using 6 pulls per second.

Ramping percent (default 500%, range 10%­500%):Adjusts how much the software helps the user. A 50% ramp will add 50% of the user’s pulling rate tothe current rate of fire. (i.e. if you pull 8 times per second, it will add an additional 50%, meaning thegun will fire 12 times per second)PSP/Millennium mode semi shots (default 3, range 1­5 shots):Sets the number of semi‐automatic shots before ramping begins in any of the PSP or Millennium modes.PSP/Millennium mode reset time (default 900 ms, range 500­2000 ms):Adjusts the reset time for any of the PSP or Millennium fire modes for when the user stops shootingbefore it reverts back to the initial semi‐automatic shots, as selected in the previous setting.G mode or “breakout mode” (default off): Tadao Technologies LLC takes no responsibility for theuser’s choice in using breakout modes.This breakout setting provides unlimited full‐auto, which then falls back to the user selected fire mode,on the 1 st , 2 nd , or 3 rd shot after turning the board on. Breakout modes are illegal for use in alltournament series and most recreational paintball fields .Rate of fire display mode (default average):1. Maximum – displays the highest achieved rate of fire based on the shortest time between any 2shots.2. Average – displays the highest achieved average rate of fire based on 3 consecutive shots.Brightness (default 5, range 1­5):Allows adjustment of the OLED display brightness. Lower settings are less bright, with a setting of 1useful for night play and scenario games.Boot screen timer (default 1.5 seconds, range 0.0 to 3.0 seconds):Adjusts how long the boot screen is displayed when the board is turned on.Auto­off timer (default 30 minutes, range 5 to 60 minutes, or disabled):Adjusts how long the board must sit idle before automatically powering down to conserve batteries.Shot counter:Displays the number of shots. Can be reset by pressing/releasing the power switch.Save/Load profile:Allows the user to save or load settings in 5 separate profiles. Both saving and loading profiles followthe same operation. Enter the setting by pressing the power switch, then use the trigger to scroll towhichever profile you want to save or load. Press the power switch once the desired profile is selected.The board will prompt you for confirmation of the save or load, and then proceed to complete theaction or, if aborted, return back to the main setting menu.Reset:Allows the user to perform a settings reset, which returns all settings to their default values. Savedprofiles and the boot screen image will not be reset.Version:Displays the current software version running on the Yakuza series board.

Tengu software:Introduction:The Tengu USB Interface is a PC application that allows you to interact directly with your Yakuza SeriesUSB board. It provides the capability to update the firmware, customize the boot screen graphics, andload/modify/save settings. Additional features are continually added to correspond with new releases ofboard firmware, so it is important that you download the latest version of Tengu each time you updateyour board: http://www.tadaotechnologies.com/productcart/pc/viewContent.asp?idpage=15How it Works:The new Yakuza USB boards are designed around the Microchip PIC18F2550, which is a specialmicrocontroller that has full‐speed USB 2.0 support, and can directly interface with a PC as a humaninterface device (HID). It is a true USB implementation and not just a USB‐to‐serial converter found oncompeting products. Since it is recognized as an HID, the drivers are built into Windows, which makes itvery easy to install.There are 2 sides to Tengu. One side is in the microcontroller on your Yakuza USB board and is called thebootloader. The other side is the user interface that you see when you run the Tengu application onyour computer.The bootloader is a permanent program that occupies a small portion of the memory on themicrocontroller, and is able to rewrite the code that runs your paintball marker. It communicates overthe USB bus to the Tengu interface. The Tengu interface is thus able to send updated firmware to theboard or modify the boot screen and settings.

The firmware files are encrypted using 192 bit AES, which is the current encryption standard for the U.S.government. The files are sent in encrypted form over the USB bus to the microcontroller, where theyare decrypted before being written to program memory. Encryption protects the intellectual property ofTadao Technologies. It also prevents abuse of the USB interface, such as players trying to write theirown cheater software.Additional InformationVersions :Due to the addition of new settings or features in either program, a specific version of Tengu must beused with each firmware release for a board. Firmware compatible with Tengu versions are listed on thewebsite: http://www.tadaotechnologies.com/productcart/pc/viewContent.asp?idpage=15Power on/off:The board must be turned off before connecting to the PC or it will not be properly recognized. Whileplugged into the USB cable, the board cannot be manually turned on. Input from the power switch willbe ignored until it is removed from the USB cable. The battery can be left plugged in while using the USBas long as the board is first turned off.If you accidentally flash the wrong firmware to your board (i.e. putting the Ego board firmware on yourUltralite board), remove the battery and flash the correct firmware.Tengu Requirements:1. Computer with a USB port and running Windows XP or Windows Vista2. 'Mini‐B' to 'A' USB cable (commonly used with digital cameras, Blackberrys, etc.)3. Windows XP users will need the Microsoft .NET Framework, available fromhttp://msdn.microsoft.com/en‐us/netframework/default.aspx. Specifically, download and install.NET Framework 3.5. Windows Vista includes the .NET Framework by default, so nothing else isneeded to utilize Tengu.NOTE: If using Windows XP, download and install the .NET Framework from Microsoft. If usingWindows Vista, you're fine!Download the latest version of the Tengu USB interface from:http://www.tadaotechnologies.com/productcart/pc/viewContent.asp?idpage=15. The executable canbe placed anywhere on your computer and does not require an installation routine. The USB drivers arebuilt into Windows.

Connecting your Yakuza Series USB Board to the computer:1. Power off the Yakuza USB board.2. Remove/disconnect the battery.3. Using the mini‐B USB cable, connect the board to the computer.4. The board will automatically be recognized as an HID USB device. Wait patiently while Windowsfinds and installs the necessary drivers.5. If necessary hum “The Girl from Ipanema” while pretending you are on an elevator.6. Windows may notify you that a reboot is required to finish installation.Using the Tengu InterfaceStart the Tengu executable. The main window is shown, displaying the About tab, firmware updatesection, and USB status message box. The tabs along the top of the window will display specificcustomization features of Tengu. The firmware update box and USB status message box are alwaysdisplayed, regardless of the selected tab.Updating Your Board's Firmware1. Turn off your board.2. Connect the board to the PC with the mini‐B USB cable.3. The USB status message box will display that a board has been connected.4. Click the “Open File” button. An open file dialog window will appear.5. Navigate to the location of the new firmware file (.aes file extension) you want to download toyour board. Select it.6. Click the “Program” button. The update will begin, with the USB status message box showingthe various steps of the programming sequence.7. When finished you may unplug the board from the computer or use other Tengu features.

About tab, firmware update completed (USB status message box):Using The Boot Screen EditorThe boot screen editor lets you create or import a customized boot screen, which is displayed everytime you turn on your board. The boot screen editor tab displays an enlarged 96x16 pixel representationof the OLED screen. The buttons along the top allow you to:1. Save the current image displayed in Tengu to your board.2. Load the current image stored on the board to Tengu.3. Load the default kanji/Tadao image.4. Turn all pixels on.5. Turn all pixels off.6. Mirror the pixels (every pixel lit is turned off, and vice versa).7. Save the current image displayed in Tengu to a bitmap image file on your computer.8. Load an image into Tengu from a bitmap image file on your computer.File formats supported:Tengu will load any type of bitmap image that is exactly 96 pixels wide and 16 pixels in height. The OLEDscreen is monochrome, so when you design images in applications such as Photoshop, you should create1 bpp bitmaps, or only use absolute black and white. Tengu will reject bitmaps that are not 96x16 pixels.Images that contain colors other than absolute black and white may not load correctly.Do not use image editing tools to resize an image down to 96x16 pixels. You will lose image quality, andthe pixel colors may change, resulting in poor translation when loaded into Tengu.

Boot screen editor tab with default boot screen loaded:Boot screen editor tab, file open dialog box:Modifying Board Settings With TenguThe settings tab lets you adjust settings on the board. The buttons along the left side allow you to:1. Select the location on the board from which to read or save settings.2. Load settings from the selected location to Tengu.3. Save the current settings displayed in Tengu to the selected location on the board.4. Load the default settings into Tengu.5. Load settings into Tengu from a file on your computer.

6. Save the current settings displayed in Tengu to a file on your computer.Note: Each version of Tengu supports specific firmware for all of the Yakuza USB boards. As newfeatures and their corresponding settings are added to the firmware, Tengu must also be updated sothat these settings can be manipulated from within its interface.Every release of Tengu is capable of updating the firmware on any of the Yakuza USB boards. However,only specific versions of Tengu will be able to correctly load, save, and modify the settings for eachrevision of firmware. The Tengu page athttp://www.tadaotechnologies.com/productcart/pc/viewContent.asp?idpage=15 contains a list ofcompatible firmware and Tengu versions.

FAQ1. Q: Can an existing Yakuza board be retrofitted with the USB port?A: Unfortunately no. The USB board has twice as many components, which may be hard to tellfrom the pictures – but they are there.Original Yakuza Circuit board on Left – USB Version on the right.Other differences:‐ New microcontroller which also uses a different pad layout.‐ New voltage regulator which also uses a different pad layout.‐ Smaller form‐factor capacitors and twice as many of them.‐ Smaller form‐factor resistors and twice as many of them.‐ Smaller form‐factor diodes and twice as many of them.‐ 3x as many transistors and mosfets.‐ And of course a USB mini‐B socket.2. Q: What type of cable is needed? Is one included in the box?A: The socket on the board is a standard mini‐B USB port. Many cameras, phones, and otherperipherals use the same cable. You may have one already so we are not including one toreduce costs passed on to the end user.3. Q: What is the direct URL to the software on the Tadao website?A: http://www.tadaotechnologies.com/productcart/pc/viewContent.asp?idpage=15 or you cando the tinyURL of http://tinyurl.com/tadaotengu4. Q: I have a really cool image that I want to use for the boot screen – any tips on the best way todo this?A: While importing images is generally problematic SpyderOWNAGE on PBNation outlined somesteps that he found to work well with importing. They are “So far, the best method I have foundis to: take an image, change it into grayscale, adjust the brightness/contrast until you get a

decent image, manually change the greys to black or white, re‐size the image until it's almost96x16, fix any newly formed greys and then transfer it to another PSD file that is already set upfor 96x16. Adjust the image to where you want and then change the mode to BMP at 96ppi.Words (that aren't logos) and paintball guns (because of all the milling) are the hardest tocreate.”5. Q: What if I just want my own text in the boot screen?A: In Photoshop or another image program make a 96x16 pixel image with bitmap color – thisshould automatically change to 1 bit color. Use the text insert tool and experiment with fonts toget something you like. If it isn’t completely perfect – don’t worry about it. Once you save thefile as a .bmp you can import it into Tengu and change any individual pixels you want.6. Q: Where can I find some premade images to use for my boot screen?A: Several users have posts in this thread with images they created.http://www.pbnation.com/showthread.php?t=2916596&page=3
