Update: A quick Popsloader bug fix:

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

The M33-4 package below contains the corrected ’seplugins/popsloader.prx’ file.

M33-4 & Popsloader 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).
• Bugfix: Games without compression had sound issues when using 3.72 pops. Fixed.
• Added support for multidisc px 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.
