I am having the same problem (sort of) with 3 different games. XIII, Topspin, and FIFA 2004 either go directly to the dashboard or in the case of Topspin it goes through a few of the first loading screens and intro movie and then boots me out right after the MS screen. Here is what I have:
I bought a pre- modded x-box locally and it has this mod on it: Exodus/Matrix no-solder mod chip (I believe version 1) with the 256k BIOS chip (*NOT* 1MB) with a 60GB 7200RPM Seagate Barracuda HDD...
I have about 12 games on the HDD that work fine (direct disk copy to hdd) and about 12 or so that I have burnt from newsgroups to DVD's. All of the others I have burnt work fine aside from me being lazy and not reading up on the FAQ's on how and what program to use for recording the titles that have been ripped for CD-R burning. Anyway... I know much of nothing about the bios's or any of that stuff. From what I understand this thing has multiple bioses loaded on it or something, but my main goal here is to find out that given the mod chip I have can I be able to run games like XIII, Topspin and FIFA 2k4 or do I need a new mod chip? If I just need a new bios or what...
