GG Game Gear Assembly Code by krom (Peter Lemon). All code compiles out of box with the bass assembler by byuu. I use a special version of bass by ARM9 which has been updated with GG Z80 output: https://github.com/ARM9/bass I have included binaries of all the demos. I used the SMS Power Offical Docs to help get me started: http://www.smspower.org/Development/SMSOfficalDocs Howto Compile: All the code compiles into a single binary (ROMNAME.gg) file. Using bass Run: make.bat Howto Run: I only test with a real Game Gear using a flash cartridge. You can also use Game Gear emulators like MAME GG Driver.
