GB Pallet X v1.1

EXPLANATION OF WHAT THIS DOES:

This is a batch file I compiled to an EXE that can set the original monochrome Gameboy ROM's default color pallet to be greyscale upon being run in a Gameboy Color or Gameboy Advance. (You won't have to manually press DPAD-LEFT + B anymore.) It works by changing the header information of the ROM and internally identifying the game as "X", which tricks the Gameboy Color BIOS into thinking you're playing the Japan-exclusive game. "X" is the only game ROM known to use the greyscale pallet by default.

This uses an embedded and unmodified version of RGBFIX to achieve this. I simply made it idiot-proof for the sake of simplicity.

HOW TO USE IT:

Simply place all the monochrome game ROMs you want to convert into the same directory as the executable, and run it.
NOTE: This does NOT work for dual-mode games that come on black cartridges, or on Color games. (This only works for original gameboy games!)
