I did a quick PPF fix, but I dont feel like really playing the game. I didnt replace videocodec, mpeg and mpegbase and it shows because there don't seem to be any movies, and since its a disney game you know theres movies. If the game crashes then the last few prx need to be replaced without moving files around.. and the only possible problem I see so far is it isn't playing movies.
Theres defenitely movies, i extracted the patched Cars iso with iso buster and took a look at the pmf files with the installed pmf codec via Mediaplayer.
The big question is, wich PRX files to use for swapping.
i think he didn't replace the prx because when i unpack the patched iso and rebuild it with umdgen it doesn't work. And the iso size is totally different (230mbs against 870mbs for the original). This iso is strange imo
