Jsmith, I had posted before, but I'll say it again.
This game works fine for all users that use any X2 or EvoX BIOS stored on a mod chip or TSOP. I'm not telling you to take either route, I'm just saying that it evidence enough for me to confidently say the problem is not with the BIOS. I genuinely think the problem is with the way the BIOSes are patched to be bootable from media, and as such there is nothing for the BIOS developers to correct. I don't use exploits, PBL, or BFM BIOS releases at all, so tell me...are there multiple ways to make a BIOS BFM? Is Xbtool the conventional way? Is it possible to manually patch it? I think that's an area that will have larger payoffs in this case.
