So now the PSX Emulator is perfect and works really fluent!!

Maybe it is time for the PSP one I would support it with donation! and i'm not the only one i think

Spec wise, the PSP is closer (read: not close to, but closer to) to PS2 than PSX, so I expect emulating it would take a lot more out of your CPU than FpseCE.
That aside though, It would be cool being able to emulate a PSP on a phone, including custom firmware and whatnot. Hell, if the emulator was good enough, it'd give you inclusive PSone emulation as well, so FpseCE would be out of business.
Anyway, moved to off-topic.

Would be really great, But I would still prefer my lovely PSP to play games with my friends xD
But I'm pretty sure that We wont see PSP emulator on WinMo. Mainly because Windows phone 7 will eat our phone resources and even newer and better phone wont be able to emulate PSX. Well Maybe Android should concentrate on PSP emulator, would go to Android Right away then xD

I sold my PSP a few years ago. Just bought one from someone on Craig's List for $15! The UMD drive doesn't work, but I don't have a need for that.

I own a PSP and there are almost no good games to play. Just my opinion of course. I would prefer 100 times more a N64 emulator than a PSP one.

If you can't find many good PSP games, then you can't have been looking too hard. I'm sure I've listed these before, but here are my favourites (including their MetaScore):

Syphon Filter: Dark Mirror (87)
Syphon Filter: Logan's Shadow (85)
Crisis Core: Final Fantasy VII (83)
Resistance: Retribution (81)
Final Fantasy Tactics: The War of the Lions (88)
LittleBigPlanet (87)
Metal Gear Solid: Portable Ops (87)
God of War: Chains of Olympus (91)
Grand Theft Auto: Chinatown Wars (90)
Grand Theft Auto: Liberty City Stories (88)
Grand Theft Auto: Vice City Stories (86)

Daxter (85)
Half-Minute Hero (84)
SOCOM: U.S. Navy SEALs Fireteam Bravo 2 (81)

Also we liked patapon, but got stuck in desert miracle which we couldnt do and got bored and annoyed with it =/

Btw, I saw an N64 Emulator for PSP, I dont how good it runs through =)

Yeah, I've used that N64 emulator, DaedalusX64. They worked for about three years optimising it, so Super Mario 64 works reasonably well (it's very playable), but most other games are still too slow. The only reason I really wanted it was for Ocarina of Time and Goldeneye, but they aren't very playable on it. It's been about six months since I last tried it, so it may well be better than I remember by now. The link above is to the QJ article reporting the latest release.

Yeah, it's too slow yet to be playable, except for Mario. Anyways I don't like most of games you posted before. I mainly bought a PSP for Crisis Core (and it's not as good as expected) and because I found a really cheap psp (about 40 euros, second hand). The DS has many better games than PSP. Anyways, I don't see the point of making a PSP emulator for phones, it would be better a N64 or even a Dreamcast emulator.

Anyways, I doubt anyone is going to do it so there's no point to discuss about that : P

the point is simply to kill time =)
And I'm so going to disagree with that PSP vs DS thing xD
