What about a Project64 PSP Emu?

It would be wonderful but psp hardware is not as good as pc's

At your service, dood!
I have no idea why people get excited about 64 emulation on a psp - I couldn't even get the genesis emu to run at 100% speed with sonic the hedgehog - PSP isn't powerful enough... lets see lets try emulating the psp on an atari 2600... that sounds equally plausable and pointless.
Letsee.. 3200mhz computer vs 333mhz psp, computer runs pj64 fine... psp runs n64 emus like crap. fast processor ftw!

You can't directly compare the Mhz's because they are different CPUs. Two different architectures and probably PSP has some additional CPUs to speed up things.
Like N64 that has 93.75 Mhz processor, sounds like shit right? But it's a MIPS processor which by architecture is better than x86, also it has the RCP which is a vector processor which makes the difference.
From Wikipedia:
Processor: 93.75 MHz NEC VR4300 (info), based on MIPS R4300i-series 64-bit RISC CPU (image)
Graphics: SGI 62.5 MHz RCP (Reality Coprocessor) (image) contains two sub-processors:
- RSP (Reality Signal Processor) controls 3D graphics and sound functions (DSP-like MIPS R4000-based 8-bit integer vector operations)
- RDP (Reality Drawing Processor) rasterizer handles all pixel drawing operations in hardware, such as:

tbh i dont know the fuss about allways getting emulators to other ports like when i got my Nokia 6600 some years back all was so excited over they could play c64,nes and sega games on it i installed some of them to see what it was about and laughed becouse not only was the tft screen so small i got a headache just trying to read the text and some of them was really slow ..
another thing if people have a decent pc why not play the nintendo on it the time and energy trying to optimize it for run at least with decent speed would take some time im quite happy the team uses thier energy on doing the PJ 64 as good as poosible on the pc ....
and i doubt you ever would be able to run "golden eye" on a psp with decent speed

I say the more the merrier! What's with all the pessimistic POV's here, yikes! Even if none of the games would run full speed - even in the future, it's a pretty damn sweet Proof of Concept.

I actually agree with Scott. You have to understand the overhead of running a multipipelined 64-bit CPU through C code on a PC. It's hard enough to get a 100% emulation on a 2 Ghz x86, but then trying to compile it for a considerably less powerful system, will only result in the need for speed hacks and degraded sound and graphics. If this obsession with porting to handhelds is so overwhelming, perhaps a crappy, hacked emulation is fine. I want nothing to do with that and I don't think the developers of PJ do either. At least, I would hope.

I like that handhelds and consoles get these emulators too even though I don't own them. It's good too see emulation is still alive.
As for an N64 emulator for PSP, it's likely never going to be great. The comment on the PSP having a more efficient processor doesn't mean much without the right coders. There are a lot more people comfortable with efficiently coding for x86 processors than specialized processors available in many of these devices. It's possible that some emulation could be simpler on a PSP than an PC system but there is pretty much no chance anything will ever run full speed and with sound. Porting Project 64 to the PSP would probably take a lot longer than rewriting a new emulator from scratch. The upside is that with the PSP you can get away with the low native 320x240 resolution of the N64 to save resources.

Pretends to make sense
Even if it was possible to emulate the N64 fullspeed on the PSP, (not likely) it would be impossible to do with PJ64. PJ64 is written for x86, probably in C++ (I'm too lazy to check). Jabo's plugins are written for an API called DirectX which is available exclusively on Windows and Xbox. So, for PJ64 to be ported to PSP all the plugins would have to be rewritten and it would still run slower than Daedalus. The only way a faster N64 emulator for PSP could be written is probably in ASM. This would require a tremendous amount of work, and it is still unlikely that it would run at full speed.

No, that's emulation at it's hacky-est. Emulation at it's finest would be those that aim for hardware accuracy and do it for the purpose of documentation, thereby not giving a damn about speed or playability, not to satisfy "on the go Joe" who is happy with something not even close to perfect.
