Hacking Homebrew Emulating a PSP

[blackjack]

Well is it possible to emulate the PSP on your computer? I was just wondering.
Imo it is not possible but tell me please

.

I say that there will be a PSP emulator with PERFECT speed arriving on February 30th.

*sigh*

Great Answer. Why isn't it possible?

iirc, the psp is very similar to the ps2 in terms of technical specs. just look at the state of PS2 emulation, lol.

State of PS2 emulation?

Buggy, graphics are missing, freezes up on almost all games (the best emulators seem aimed at making Final Fantasy work before any other game), and a framerate that would make a baby's cry seem like fun.

When you're getting 15 FPS on a high end computer, you know we're a long way off.

I think the PSP should be much easier to emulate.
It's nowhere near the power of PS2 IMO.

It's like comparing a Nissan Micra with a Dodge Viper. They both may have the same RPM (MHz), but I think we all know which is faster

The PSP is just able to show pretty graphics

Pretty sure PCSX2 is now alot faster and better that what you're suggesting.. Then again I don't have a powerful system to test it on

60 fps on Final Fantasy 10 on PCSX2 0.92 here but I dont want to play it untill they fix the FMVs. Would you believe they were working in the earlier version but now they arent. How annoying

Wasn't there some news recently about a PSP emulator being in development and running some games already? I wouldn't expect too much any time soon, though.

Isn't PSP 32-bit, while the PS2 Emotion Engine is 128-bit? I think the PSP should be much easier to emulate.

Well, you are right and wrong> Real psp emulator is in the work! Do not asked him when!

Okay, here's the deal.

The PSP has ****loads of encryption all over it, making real emulation very very hard or impossible. I have tried, and succeeded, somewhat, using a more HLE approach. Information was gained from the ps2dev/pspdev project, and a little bit of reversing. The problem is that there are so many goddamn Sony libraries that have to be reversed and implemented, and with Sony releasing new functionality in every firmware it's impossible to keep up.

Another problem is that newer games don't include unencrypted binaries on the disc. For some reason unknown to me, the first hundred games or so did. Any later games are not going to work, unless the corresponding PSP firmware is hacked so that it can be used to predecrypt the binaries.

Anyway, some simple games are running. Check it out:

They're running about 50%-100% with an interpreter, but that's just because these games are so stupidly simple. More complex games would run a lot slower, but there's huge potential for good dynarecs on PSP. PSP, ignoring the problems of unknown hardware parts and unknown system libraries, is probably much easier to emulate at good speeds than the PS2.

Still, the problem of ever-increasing numbers and nastiness of librares, some completely unknown hardware (the media decoder stuff) etc make it near impossible to do a real emulator, as I already stated above.

I have not decided whether it's worth releasing.

Don't post this as front-page news either, this isn't an official announcement or anything.

See?

from the sounds of it it seems psp emulator can play only the simplest of games. i think i'll pass, thanks

That's one game and a 2D game. 3D has always been a pain and much more difficult to do. Besides, sound is also going to be a pain.

Unless an emulator coder gets his/her hands on a devkit, you won't be seeing an emulator any time soon.
