Homebrew developer NJ just unleashed a massive update for his emulation projects  on PSP, bringing them all to version 2.2.1. The emulators included in this release are CPS1PSP, CPS2PSP, MVSPSP and NCDZPSP. The first two are for Capcom Play System 1 and 2 while the last two are for Neo Geo MVS and Neo Geo CD.

Much like the previous releases, NJ has made all of them compatible with the new PSP Slim & Lite running on CFW 3.71 M33. The following changes were done as related by the coder himself (translated using an online language engine):

• Everything: When failing in opening the ROM file, because processing is strange, correcting the bug which has been frozen.
• MVSPSP: Correcting the bug which sound has stopped being played back at portion of the game where cash had become unnecessary.
• MVSPSP: Correcting the bug where the character transforms with the small game of size.
• CPS1PSP and NCDZPSP were added, but because it cannot guarantee operation, please acknowledge.
