Sony and game publishers have started to implement a security system for PSPs that block custom firmware from within the game. They do it by checking your firmware version before booting the actual game. Currently there is no work around for this (the version.txt method doesn’t work with newer games). 5.50 GEN-B and the older 5.00 M33 simply don’t work. The only way you’ll get to play these games are to upgrade to the latest official firmware.
With this kind of DRM getting rolled out, the PSP Go is starting to look very attractive.
Here’s a list of PSP Games that block custom firmware
- DJ Max Portable: Clazziquai Edition
- DJ Max Portable: Black Square
- Pangya (K)
- Idolmaster SP (Missing Moon, Perfect Sun, and Wandering Star) (J)
- Kidou Senshi Gundam: Senjou no Kizuna Portable (J)
- Evangelion Jo (J)
- Armored Core 3 Portable (J)
- Shinseiki Evangelion: Battle Orchestra Portable (J)
- Musou Orochi: Maou Sairin Enhanced Version (CH)
- Tales of VS. (J)
- G.I. Joe: The Rise of Cobra (U)
Games with specific firmware requirement:
Important Note: Most of these games will work with 5.00 M33, 5.50 MHU, 5.50 GEN-A, 5.50 GEN-B, 5.03 GEN-A and 5.03 MHU if you use the Game Decrypter.

Im running 5.50 MHU, does anyone know if I can go to 5.50 Gen-A or Gen-B from there?
I was able to get Persona to work on 5.50 MHU using game decryptor and umdgen.
Thanks for the tip
will add it to the post.
You can find the tutorial here
http://www.pspgen.com/tutoriel-game-decrypter-yoshihiro-article-190008-1.html
Already got one
http://www.atmaxplorer.com/2009/09/play-games-that-require-ofw-5-55-and-6-00/
But it does not mention using file->file lists-> export before decrypting the eboot.bin and using file->file list->import after adding the decrypted eboot.bin. This was the extra steps I had to take to make sure Persona worked.
Missed that… will add.
* For these games, you must export the file list of the original game with UMDGen (File-> File List-> Export), patch the game as explained in the tutorial, then with iso patched, forcing the list of file Designating one that you exported (File-> File List-> Import).
This list is not complete, it will be completed as and when the test, feel free to post comments, noting the differences that you osbervé in this list, not forgetting to mention your model PSP and the cfw on which you tested.
Fate Unlimited Codes [USA]: Works with 5.00 M33-6 without decryption.. same goes with Dissidia Final Fantasy [USA]
Tales of Versus[JP] Boots when decrypted but gets stuck at the black screen (can exit the game with the home button)
persona does NOT work on 5.50 MHU.
it works on 5.03 MHU, but 100 percent NOT on 5.50.
Everybody I know used Gamedecrypter + UMDGen + EBOOT patcher with no success.
If you, modok claim to get it working, would you please post a proof?
Or, how did you manage to do it?
Yeah I had to do the file -> export file list before decrypting and after putting the eboot.bin back into the umd I did file -> import file lists.
