Not a problem to emulate

I've been waiting for this ever since emulation on the PSP was first announced!

Capcom defined the arcade experience all throughout the 80's and 90's.

In my rudimentary understanding the NeoGeo and the CPS boards both use a motorolla M68 chip, so I have really been hoping NJ would move his programming talents in this direction.

Even if CPS2 runs like NJ's NGEPSP running sprite graphics off the memory stick stuttering here and there, I'm totally cool with that. Everything doesn't have to be perfect NJ.

Damn the PSP is such a sweet little machine.
Tons of great emus, and now we're finally getting gereat UMDs like Tekken and Ghouls and Ghosts.

Oh yeah, and as far as I know CPS2 is decrypted. It's CPS3 that's never been decrypted.

Wow this emulator sounds like nothing but good news, but I have to say I have been looking over the specs for cps-2 and I don't really understand on why it would not be able to be emulated on the PSP. But great work NJ ^_^ I have to say though there is just one feature I wish you always added to at least one of your emulators, and that is multiplayer support I wanted to play Metal Slug multiplayer with my m8s a lot but I can only hope and dream right =P

I was just checking on that. Your right its CPS3 not decrypted.CPS2 is and mameuser was nice enogh to give the correct specs. he beat me to it.
But ther is no CPS2 emu for any counsil at the moment. Unless mi recolection is wrong.

There is no CPS2 specific emu. Just multi-arcade emus that support CPS2 games.

MAME (everything)
Nebula (Neo Geo, CPS1, CPS2, crystal board)
Kawaks (Neo Geo, CPS1, CPS2)
Final Burn (Neo Geo, CPS1, CPS2, other random drivers)

There is CPS2 specific emu.

1: Calice (Discontinue)
2: ACE (Discontinue)
3: CPSE (Discontinue)
4: more+

ooooh, don't get my hopes up guys. it'd be a dream to run a CPS2 on the PSP. i'm getting clammy just thinking about it.

Perhaps as there is no actual CPS2 emu for NJ to port, building it up might dig up some real gold.

Forgive me though, i'm not familiar with coding in the slightest so my understanding of all this encrypting/decrypting, CPU, free memory or whatever is very foggy.

I'm just one of the hungry wolves that chews on the kill at the end.
