Persona 3 Portable(USA)

Why would we need to make it work with a patched ISO for pirates when you can just use an unpatched ISO instead ? We're not doing this to help people pirating games.
If you can apply the prometheus patch, you can also use a valid ISO. And if you can't play the game, you just have to buy a newer PSP and use it with your UMD. There's no absolute answer for every problem, and Jpcsp isn't here to palliate the PSP FW problems (or lack of money to buy the console and games).

Okay, I can confirm ISO TOOL 1.74 (i just updated to 1.75) does not modify the lba table when rewriting the decrypted file back into the dumped iso. This means we can avoid using umd-gen altogether for decrypting files LMAO. Also instead of using umd-gen, which you need to export file list to maintain lba when reintroducing files sometimes, WQSG_UMD Tool, It allows one to import files without having to worry about the lba issue. I should start a thread to discuss this as a tutorial. but... BACK TO TOPIC.

Actually NO, so far you do not need to buy a newer psp in order to play the newer games. Promethus Patch allows a user of an older firmware like 5.00 m33-6 to play the 6.10 - 6.30 ofw games, for the newer firmwares. YOU CAN DUMP A NEWER GAME ON AN OLDER FIRMWARE, BUT YOU JUST CAN'T PLAY THAT SAME GAME WITHOUT THE PROMETHUS PATCH APPLIED.. My suggestion had nothing to do with piracy, but to make the process more convient for people who dump from UMD games.

Well to be honest, I don't like to redump games, if i have 1 version of it stored somewhere, even on my psp LMAO. Instead, i'm going to make ZDELTA PATCHES for all my UMD BACKUPS, when i apply the PROMETHUS PATCH (last time i checked its 0.6 beta). No still no better results with Persona 3, and I can play this game on 5.00 m33-6 on my phat if i update from 3.90 m33. Which i believe i can do directly with dark-alex's update and a 5.00 ofw update file. I just don't care for the newer firmware, however I'll update again though.

Persona 3 is pants so far, until a new revision of the emulator. The original poster of this thread, was probably offended at the suggestion that he was into "piracy", and probably choose not to reply to this thread. Thats something i used to do, but its not the mature thing to do.

EDIT

If you like your homebrew apps like me, some apps don't work on newer firmware and some emulators bug out, then your likely a promethus patch user, although I'm not really interested in the newer games as of yet.

EDIT

I found out how to undo a prometheus patch, so that the game works with jpcsp emulator without redumping the game read the bottom of the first post in this thread
