I bet it's extremely hard I mean the second processor is for sound and just like yall said it's used for async but is usually unstable but doesn't cause emulation to slow down but idk if it's possible to use that 2nd processor for graphics since its only used for media but it's also used for video i think I mean all around media peroid on the psp correct me if im wrong.

I sent kreationz a private message a while back and asked him if it was possible and he said yes but it would be extreamly difficult. He said also that he wrote a program that actually made the psp ME and normal cpu run both all the way and he said that there was no mess ups with the console (he left it on for a long time) he said the only thing was the battery. But i would take no battery life for fullspeed portable N64 ;D

PS I think daedalusx64 can reach fullspeed without it. Sure not every game but i think games like ocarina or majora's mask could reach fullspeed look how far they've come...

Well the psp is still very usuful on some n64 games, homebrew games, and just psp games and internet and stuff like that and media etc but it's still a good device one day we're all gonna be playing ps vitas and stuff and the psp will be old news til someone brings it up again. Anything can be done maybe a beta 4 you will be able to enable 2 cores and just play n64 games easily at a smooth framerate I think zelda might slow down just a little bit in some spots and im sure it will be very unstable at first if it was officially ever done. There's a possibility it can be done though cus he said yes. Just imagine how hard it was just to emulate super mario 64 at full speed on daedalus and look at it now it runs pretty smooth slows down just a little bit and it used to run like crap on the first revs and now it's amazing its amazing how far they came.

i know I couldn't do it if I figured out how to make apps and stuff for the psp and if i actually made an n64 emu for the psp im sure I couldn't get it to go full speed at all.

I've heard a while back in "psp2 processor" that there are two processors for the psp I already knew there were 2 processors but they said that the 2nd processor can be used to take advantage of the speed in daedalus im not sure how fast the other processor is but if there was someway a new revision could be made to take advantage of this 2nd processor im sure we would see faster game play and if not full speed im sure it will still be playable I mean it will be faster than what it is now im sure.


First of all, the PSP doesn't have a second processor. The ME is a Co-Processor which isn't meant to be useful for other than playing audio.
And the task to run any code in the ME is eye beading, a great developer called Howard0su (which contributed pretty much all the improvements of Beta 1 and Beta 2), actually stopped working in this project since he got frustrated with the ME, is a (nearly) impossible task to be done, don;t expect it anytime soon.

The psp has 64mb of ram and lol I already have project 64 for the pc the recommended speed of the cpu to run ultrahle is 300 mhz the psp is clocked at 333mhz but games on ultrahle were going fast they were playable on slow processors that clocked at lower speeds than the psp's cpu and they still went faster than the psp.


The PSP Slim+ has 64MB, Phattys don't, so keep in mind we have to support both models, anyways Daedalus was coded to work fine with 32MB (it's actually less if you take in account the OS etc), and more memory won't speed up anything. Read this : http://strmnnrmn.blogspot.com/2007/10/d ... -lite.html

And don't compare the PSP CPU to anything available for PC, PSP hardware lacks alot features needed for proper N64 emulation, ex branch prediction, doubles, MMU, very small instruction cache/pipeline etc.

Anyone remembers how a Pentium 4 clocked at 2Ghz beat a Celeron clocked at 3Ghz? I'm sure you get the idea.
Also you can't compare UltraHLE to modern N64 emulators, you can get the idea of speed over compatibility.

@@RuffBad: I never saw any code from Kreationz that ran any code other than audio on the ME, so don't hold your breath.
The closest thing I ever saw was Howard0su's ME WIP which ran a few fragments of the dynarec.
