Monster Hunter Portable 3rd

If you use files from tpunix to run the game, he said there are only 13 out of 17 files out there since he couldn't find where are the others in game. Black screen is probably caused by one of those missing files. You'll have to use real PSP and the tools from this pull request to decrypt the missing file(it should be automatically created in "memstick\PAUTH" when encountered the encrypted texture in game), you might also have to repeat that procedure as there are in total 4 files missing in tpunix pack as he said himself in that pull request I linked, some of them might just cause black/empty texture, others freeze the game.

Before doing anything, you can easily check if that is the case by looking in your "memstick\PAUTH" folder, in tpunix pack there were 39 files(13 files decrypted with bin and key files) if you have more files there, then that's more than likely that you encountered one of the missing ones.
