I found some cheats for a game I'd like to play, but they are in a weird format which isn't supported by pj64 1.6 , apparently they changed the format for 1.7 and encrypted the cheat which were standard before. That's some really nasty thing to do :-/

here are the cheat (hmm attachments seem to be broken here)

Alternatively if you know where I can find the raw cheat for that game, please let me know.
