Yeah, we have been having some problems getting this to work on all ROMs, Iv'e only been able to get it to work on an old ROM from coolrom.com. Make sure it's a fully clean rom, not even extended and try it. Also make sure it's a USA ROM, as that is what we used to create the patch. When we release the final version, we will be including a pre-patched version on media-fire or something, so we won't have to worry about this. Sorry for the problems.
