Anyone using a EFA 512 and Mac OSX? I just ordered one. Have a PC, but would rather use my Mac. Is it true you can just drag and drop ROMS into the cart like an SD card? Also, I have some ROMS but I don't know if they are good. They came as zip files, and my comp unzipped them. Now they are Folders.... with lotsa stuff in them. Should I look for the file ending in .gba? I have an R4 and I know DS roms end in .nds, but do I want GBA roms ending in .gba? Just trying to get things together so I can have fun when the EFA comes in the mail. Any help would be super-dee-duper!!!
