I can't post a link to the file here because it contains the Super Gameboy 2 ROMS. xiaNaix told me today that SD2SNES and SD2SNES Pro both support Super Gameboy 2 now and you can load gameboy ROM files directly from your SD card now. The author of the SGB addon functionality to SD2SNES is unknown at this point and this is a first release so expect that there may be some bugs.
