Monster Hunter Portable 3rd

@Juz_Kiddin' to me this looks like missing pauth files. If you could even boot the game, you probably used a savestate made on version in which you had those pauth files. Make sure you download the pack shared here or search through this thread for guide how to decrypt your own files using psp.

If you can afford it you could always buy the HD release of the game for ps3, since it works pretty much same on PPSSPP when it comes to performance, has a few slightly higher res textures resulting in nicer graphics and what's important, nothing is encrypted there, so it works without those pauth files. The game shares saves, dlc's and even multiplayer, so it's not complete waste of money especially if you have someone to play with. This solution through except extra money for exactly same game ofc requires to either have a ps3 or bluray drive for pc which reads ps3 games discs(afaik not all of them can).
