OK,

Well, I started doing this, but about 40% through the file I realised a few things:

1:  It's incredibly tedious doing this.
2:  While a few people may be interested in the technical details of fixing things, they probably wont use any of the information to patch anything themselves.
3:  Each title is different, so all it would teach you is how to fix Chuck Rock.
4:  It wouldn't even teach you that because the loader and the actual cracking/fixing are seperate things.
5:  I'm a tad busy and distracted at the moment for other reasons.

So... I guess you have the source code for my loader - enjoy :)
