I'm having a problem with this as well. I'm usually pretty good about getting things to work, but this is giving me some trouble. I'm about 70% sure its because I have save files for an older version Surreal somewhere on the harddrive (or other Cache/Temp/Save files).
When I try to load any rom, on any of the 3 emu's within surreal (the latest beta, same problem with the previous release), it loads then goes to a black screen. Tried messing with some settings, nothing works. In game reset is disabled on the dashboard, and I've tried using two different Bios (the recent 5028, and the last stable release).
Any ideas? Could someone tell me some other places that Surreal files are located? I'm considering formatting my xbox harddrive sometime soon, because things are really messy. I've noticed that a lot of xport emulators appear in my gamesave manager under "Xboy Advance" (GBA emu).
Thanks.
