+Gambatte-DMS emulator 
+------------------------------------------------
+
+Gambatte is an accuracy-focused, open-source, 
+cross-platform Game Boy Color emulator written 
+in C++. It is based on hundreds of corner case 
+hardware tests, as well as previous documentation 
+and reverse engineering efforts.
+
+
+Default Ingame Controls
+------------------------------------------------
+
+D-PAD               D-PAD
+B Button            B Button
+A Button            A Button
+Select              Select
+Start               Start
+R trigger / POWER   Menu
+L trigger           Fast Forward
+
+
+General Menu Controls
+------------------------------------------------
+
+D-PAD               Move cursor
+B Button            Go back / Cancel
+A Button            Select / Perform action
+
+
+Save States
+------------------------------------------------
+
+There are 10 savestate slots available per game.
+There are options in the menu for loading and 
+saving states.
+
+The default slot is always Slot 0.
+
+The default slot will always be selected when
+starting the emulator. Selected savestate slot 
+will not be saved on emulator exit.
+
+
+Emulator Options
+------------------------------------------------
+
+Here is a list of the available config options:
+
+- Show FPS:
+    Shows or hides the FPS counter.
+    Default is "Off".
+
+- Scaler:
+    Allows to select between a range of scalers.
+    Default is "No Scaling".
+
+- Mono Palette:
+    Allows to load external palette files for 
+    use with monochrome GB games in DMG mode.
+    The "Auto" option will try to find a palette
+    with the same name as the ROM file, and it
+    will load the default palette if it fails.
+
+- Color Filter:
+    Allows to load external filter files for 
+    use with color games in GBC mode.
+
+- DMG/GBC border:
+    Allows to load external PNG border images
+    for use in DMG/GBC mode.
+    The "Auto" option will try to find a border
+    with the same name as the ROM file, and it
+    will load the default border if it fails.
+
+- System:
+    Allows to select the system priority when
+    a ROM supports both DMG and GBC modes.
+
+- Boot Logos:
+    Allows to use GB/GBC BIOS files to display
+    the splashscreen logo when loading a game.
+
+- Ghosting:
+    Enables or disables frame mixing to mimic
+    the DMG LCD ghosting.
+    Default is "DMG only".
+
+- Controls:
+    Allows the user to tune the controls.
+
+- Sound:
+    Allows the user to select between Mono and
+    Stereo sound.
+    Default is "Stereo".
+
+
+Palette files
+------------------------------------------------
+
+Palette files are text files with the extension 
+".pal" and its format must be:
+
+0xRRGGBB 0xRRGGBB 0xRRGGBB 0xRRGGBB
+0xRRGGBB 0xRRGGBB 0xRRGGBB 0xRRGGBB
+0xRRGGBB 0xRRGGBB 0xRRGGBB 0xRRGGBB
+
+Where each line is a separate 4-color palette
+for each sprite layer, and the color order is:
+"white" "light-grey" "dark-grey" "black".
+
+
+Filter files
+------------------------------------------------
+
+Filter files are text files with the extension 
+".fil" and its format must be:
+
+a1 a2 a3 a4
+b1 b2 b3 b4
+c1 c2 c3 c4
+
+Where each value is a decimal number, ranging
+from -255 to 255 which gets applied to the 
+GBC colors using the following algorithm:
+
+Rfinal = ((( R*a1 + G*a2 + B*a3 ) >> 8 ) + a4)
+Gfinal = ((( R*b1 + G*b2 + B*b3 ) >> 8 ) + b4)
+Bfinal = ((( R*c1 + G*c2 + B*c3 ) >> 8 ) + c4)
+
+A general rule to avoid the resulting colors
+exceeding the valid RGB range of 0-255 is that
+the sum of the 4 values in a row should always
+be between 0-255.
+
+
+File Paths
+------------------------------------------------
+
+- Emulator Settings are saved in:
+    $HOME/.gambatte/settings/
+
+- Savestates and game saves are stored in:
+    $HOME/.gambatte/saves/
+
+- Palette files must be stored in:
+    $HOME/.gambatte/palettes/
+
+- Filter files must be stored in:
+    $HOME/.gambatte/filters/
+
+- Border images must be stored in:
+    $HOME/.gambatte/borders/
+
+- BIOS files must be stored in:
+    $HOME/.gambatte/bios/
+
+- Valid BIOS filenames are:
+    gb_bios.bin
+    gbc_bios.bin
+
+
+Cheats
+------------------------------------------------
+
+Gambatte supports Game Genie and Game Shark
+cheat codes. Each cheat system has its own menu.
+
+Game Genie cheats:
+------------------------
+
+Game Genie codes can have 6 or 9 digits. They 
+are applied once each and they can only be 
+disabled by exiting the emulator and reloading 
+the ROM.
+
+To introduce a code, go to the Game Genie menu, 
+highlight a code line and press A to enter edit 
+mode. While in edit mode you can change the 
+value of each digit by using the D-Pad.
+When you're done, press A to save the changes 
+or B do discard them.
+
+If you're introducing a 6-digit code, just leave
+the last 3 digits as zeroes and your code will 
+be detected as a 6-digit code. If all digits are 
+zeroes, the code is ignored.
+
+There are up to 20 lines for introducing several
+codes at once if you need to.
+
+To apply the cheats, press Start, and then 
+confirm the action by pressing A. The codes will
+then be applied and the code list will be
+cleared.
+
+Cheat codes are not saved on emulator exit.
+
+Game Shark cheats:
+------------------------
+
+Game Shark codes have 8 digits. They can be
+enabled and disabled at any time.
+
+To introduce a code, go to the Game Shark menu, 
+highlight a code line and press A to enter edit 
+mode. While in edit mode you can change the 
+value of each digit by using the D-Pad.
+When you're done, press A to save the changes 
+or B do discard them.
+
+If all digits are zeroes, the code is ignored.
+
+There are up to 20 lines for introducing several
+codes.
+
+To enable the cheats, select the slot on the 
+left of the codes and press A to toggle the 
+desired cheat on and off. An empty slot means 
+the cheat code is disabled, while a check mark
+means it is enabled.
+
+Cheat codes are not saved on emulator exit.
