I was wondering how do you do this. I tried a few different ways with the Genesis Plus, SNES9X GX, and FCE Ultra GX. I burned the roms as a data disc for each one by just dropping all the roms in there without a folder. Didnt work. THen I tried using the format of how you would when you put the roms on a SD card. Didnt work. I don't know what I am doing wrong. I am using the Roxio program and using Verbatim DVD-R discs. If anyone has any solutions it would be greatly appreciated.
