Oh, my bad… It wasn’t an M33 firmware check. It was a Slim (hardware) check. To quote NoEffex –

The author separated the slim and the phat builds, and did a hardware check. If someone tried to run the slim build on the 3k, it would not work, because it doesn’t pass the slim hardware check, and as such wouldn’t be able to fully utilize the 64MB of RAM that the 3k has, and is a lot slower.

So, what I did was simply remove that check and that way you can use it on your 3k (Or anything newer for that matter). It’s not GEN/M33, it’s hardware.

The 00’s are sooo M33; that said, my main man NoEffex has re-compiled and re-released 3 rounds of NJ emulators with the M33 check removed: the Capcom CPS1 & CPS2, as well as the Neo Geo MVS.

Simply said: you can now enjoy these classic arcade systems on your Slim (PSP-2000) or 3000 using custom firmware 5.03 GEN-C.

They’re notably faster than PSPMame, too.

Faster than executing a successful hadouken, developer NJ releases yet another set of updates. 2.2.2 is the new version number for Capcom Play System 1 & 2, and the Neo Geo MVS / CDZ emulators.

Classic arcade-style Street Fighter will no doubt trigger some childhood memories; you know, the good ol’ days in those dingy arcades with the dude wearing a green visor dispensing quarters & dime bags.

Google translated changelog:

• Way it draws UI at everything GU, modification.
• English integrating the binary of edition and Japanese edition. When the indicator language of PSP itself is Japanese, with Japanese, the other than of that is English.
• With PSP-2000 the Home button was made enabled. The time before you open the menu similarly with the Home button.
• Because the clear range of VRAM when initializing by mistake was, correction. Whether this was unstable with cause.
• CPS2PSP/MVSPSP: When with PSP-2000 it sleeps, because there were times when portion of graphics is destroyed correction.
• CPS1PSP: When it compiles with psp-gcc-4.1.0, because it cannot start [supamatsusuruboma], way psp-gcc-4.0.2 is used, modification.
• CPS1PSP: Because there was the ROM set which has forgotten to correspond with final fighting spirit correction.
• CPS1PSP: Because there was a problem in drawing of the stars layer, correction.
• MVSPSP/NCDZPSP: Interruption processing of picture modification to up-to-date MAME wind.
• In addition detailed bug correction and the like.

Gotta give NJ his props… NJ has updated his entire emulator collection to version 2.2.1. We have the old Capcom Play System 1 and 2 (CPS1PSP & CPS2PSP), as well the Neo Geo MVS and CDZ consoles — all compatible with Sony’s PSP Slim running CFW 3.71 M33.

NJ is bidding farewell to the PSP homebrew scene, and as a departing gift he has left us with v2.0 of his sought-after emulators. Now, I’m well aware we have never posted any of NJ’s emulators in the past, and to be honest I have no reasonable explanation as to why… But, what better time to show respect to the highly skilled homebrew developer.

Featured in the archive:

• CPS1PSP — CAPCOM CPS1
• CPS2PSP — CAPCOM CPS2
• MVSPSP — Neo Geo
• NCDZPSP — Neo Geo CDZ

All 4 emulators come as v2.0 with multiplayer support via Ad Hoc WiFi. The source code is also included. Awesome job NJ, take care.
