I'm no n00b to emulators, and I'm pretty eXperienced when it comes to running them on the Xbox. I was about to do a softmod for someone, but rather than coping 1 - 2GB of data to their hard drive, I thought I might see about just making an emulators + roms DVD-R with MXM as the launcher. Everything seems to work fine, except FCU Ultra v16 doesn't want to run a lot of roms that it worked with before off the hard drive. If I boot from my emulator DVD-R, some games (like The Legend of Zelda) just quit back to the rom selection screen, or sometime crash the system. What's weird is it does this even if I browse to the roms on the hard drive. If I boot off of the hard drive, and run the FCE Ultra I have installed there, all the games off the hard drive seem to work again, but I still can't launch the ones on the DVD-R. Is there some other place FCU stores its configuration other than in the .ini file? Maybe something is being cached and needs to be dumped. Any ideas?
