Homebrew developer Dark_AleX has released an update to custom firmware 3.71 M33. Update 3.71 M33-4 adds full support for multi-disc PSOne games and includes various bug fixes concerning popsloader. The full changelog can be found below.

– 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 0x80000004
when attempting to run multidisc games.

The updater can be run on any previous edition of 3.71 M33. To install, simply copy the UPDATE folder included in the archive over to PSP/GAME and then launch the update from the Game menu.

Update: Dark_AleX has released a small update to the new popsloader, fixing a minor bug:

When selecting a firmware for a multidisc game, the setting was being remembered for any other multidisc game too.
