It wants the CON, nothing else, thats the file that comes from your xbox. The searching algo is still buggy, I've seen it fail on files that worked before, it shouldn't though.
It's going through a redesign to make it easier to work on in the future because right now it's a bit of a clown car.
I'm also going to hop back onto using the WPF version because it's pretty, I've added a branch to my repo, check it out if you like.
Been busy with other projects but I work on this one from time to time.
Still can't get it to support inserting bytes, damn serialised data and it's static sized values...
