I've been having problems with these games too.
My xbox is broken so cant play on the xbox version of mgs2
and the 360 doesnt back support it, anyway back to why im posting.
I noticed the main user patch thread says not the request a patch making, so i noticed the FAQ listing a link to
Nachbrenner's Site for making Patches but all i get is a 404 error. Anyone know where its gone or anything similar. I can just about get by coding with abit or a guide so i'd like to try and make an MGS2 patch.
