Playstation Portable Custom Firmware 3.71 M33-4 | PSP CFW 3.71 M33-4 by Dark_AleX
Here’s the changelog:
– Bugfix: Multidisc psx games bought in the psn store would not work due to the format being different
and M33 treating them as decrypted games.- Added support for decrypted multidisc psx games created with popstation_md (supplied with this release).
Included in the package is a new version of popsloader.
Changelog in popsloader:
- Bugfix: Games without compression had sound issues when using 3.72 pops. Fixed.
- Added support for multidisc psx games created with popstation_md. Note: multi disc games will
only work in 3.71 and 3.72 pops. Previous pops will exit to the xmb with generic error 0×80000004
when attempting to run multidisc games.
- Download: PSP Custom Firmware 3.71 M33-4
Installation is rather simple, just place the update UPDATE folder included in PSP/GAME and then launch the update from the XMB Game menu.
(Can only be run on previous versions of 3.71 M33)

“FAQ about multidisc games.
- How can I change the disc?
The disc change option is usually in grey until the game asks you to change it.
Sometimes the option may be in white even if the game doesn’t ask a disc change.”
there’s no such thing as described when i want to try changing disc in FFVII..
-no disc change option-
why is it?
-i’m using CFW 3.71 M33-4-
thnx

September 14, 2008 at 10:45 pm
the login error (949) is not because of the M33-4, its only because you got booted, you either have to wait a week, or 2 till your able to log back in, this is a response to KP
