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.
