Hi Xbuser (and everyone else) I had the EXACT same problem that you describe, and for a little while I was convinced that Final Burn didn't work... However, it's coded by the AWESOME NES6502 (thanks SOOOOO much for ZSnex NES!!!), so OF COURSE it works. Here is how I fixed the problem and hopefully it might work for you too Xbuser. Firstly, as has already correctly been suggested by fumanchu, make sure you have the right ROMs, but equally importantly, be careful HOW you transfer them onto your Xbox. When I FTP'ed them to my Xbox, for some reason, all the directories and ROM names were changed into CAPITAL letters. As soon as I deleted these, and re-transferred using XBMC (samba) the directories and ROMs were all back in lower case and.... Hey Presto!!! IT WORKS!!! :D Hopefully this might work for you too Xbuser? One quick question for anyone who might know - are there any analog settings for Final Burn, as analogue steering on Turbo Outrun, Power Drift etc etc would be SOOO cool. Cheers!
