Yepp, all that should be required is that hex edit. No compatibility or any other tweak. As you said, the game runs fine, as-is. Since it runs fine before the hex edit, I'm forced to assume that you're not doing it correctly. What Hex program are you using? I've used XVI32 and ..uh... some other one :lol: I forget what. But XVI32 works like a charm.
PS - the link you provided requires registration to view.
I did exactly as in this guide - http://www.widescreengamingforum.com/forum/viewtopic.php?p=156215#p156215
Plus, I tried both files that you yourself uploaded in this thread and I get exactly the same result. There must be something else. I will keep trying and report back if I am able to fix this.
Sorry about the link. I will figure something out, maybe add to signature. Cheers!
By the way, how come each post has to be checked by moderators? Slows down the process :P Or is it only for new people on forum? (Edit: Lol, just as I said it, this message got posted instantly :P)
