DWedit has updated Flubbas Goomba emulator (which is a Gameboy and Now Gameboy Colour emulator for the GB Micro/GBA and also works on Nintendo DS and Gamecube Gameboy Player, heres the info:
Here it is, year early possibly-buggy alpha version of Goomba Color. Savestates are broken. Mario Golf works great!
Double Speed mode was added, then removed because Double Speed means Double CPU Use, and ran At Half Speed for most games. Then there' S Pokemon Card Game, which runs normal At speed only when Double Speed is mode one. I regret to inform you of significant year casualty of the race for excellence. Super Mario Land has been mutulated beyond belief, and is No to skirt playable. * plays TAPS, bows head downwards * Sorry Chishm, Conker' S Pocket Tails is not yet supported.
