Playstation Emulator for PSP Released

Joan Cross writes "Today sees the release of the first Playstation Emulator for the PSP to play commercial games; the emulator plays games such as Ridge Racer at up to 10fps, and once dynarec is added full speed is easily in grasp. The emulator works on all PSPs except those with firmware 2.80 and higher." Update: 09/26 12:19 GMT by Z :Fixed dept.

I seriously doubt it.

once dynarec is added full speed is easily in grasp.

Yeah right. The authors of the PSP SNES emulator basically stated that even with dynamic recompilation and a full rewrite, they could see no more than a 10% speed increase over what they already have, which is playable, but not full-speed.

Somehow I highly doubt that the PSX emulator (at least the homebrew one) will accomplish that feat.

Absolutely right. Running MIPS code at full speed on a MIPS CPU is clearly impossible, even with a 4-5x clockspeed increase. It'd be like running win32/x86 apps at full speed on Linux/x86 - as if that's ever going to happen!

Running MIPS code at full speed on a MIPS CPU is clearly impossible, even with a 4-5x clockspeed increase.

Running MIPS instructions on a faster MIPS core isn't the problem. It's emulating the support hardware of the Playstation -- the sound hardware, the Geometry Transformation Engine, the Data Decompression Engine et al -- that requires a lot of overhead, and has to be done mostly in software. Even where the PSP hardware offers a close analogue, you'll need at least twice the power of the original Playstation, to translate the opcode and then execute it.

Dynarec (while being a pretty cool little contraction) has rarely brought the speed emulator authors promised. I'd like to see the authors of this emu blame its slowness on my hardware not being up to snuff.

License Violations ahoy!

[TheBlueCrab]

This emulator is a deriative work of PCSX (see the linked forum post), as well as the P.E.Op.S Soft SDL driver, and SDL itself. It violates the license of all three of those by not releasing source or an offer to get the source. (Heck, it doesn't even acknowledge that its a deriative work of any of them.)

Yet last I heard...

From Engadget:

...users of [firmware versions] 1.5 and above obviously requiring the eLoader exploit.

...which still requires editing of savegames, which still requires a copy of GTA, which still isn't legal (at least according to SONY). Why can't SONY come out with their own, viable version or a PS1 emulator already? Besides, who wants to play these games at a max of 10FPS when the human eye can see at a solid 16FPS itself?

Re:Oooh, a groovy 10fps!

C'mon, let me hear you say it.

"It's Ridge Racer! Riiiiiiiidge Racer!"

No, not that...the other thing.

"The Playstation 3 shall retail for... $599!"

WRONG!

Did someone say "Ridge Racer"?

[Yvan256]

[...] the emulator plays games such as Ridge Racer at up to 10fps

Riiiiiiiiiiiiiiiiiiidge Raceeeeeeeeeeeeeeeeeeeeeer!

Sounds familiar.

Games originally published years ago on another system that you can now play on the PSP with really bad frame rates? Isn't that a lot like 80% of the PSP titles out there? Still, portable Parappa would be pretty amazing...

Re:Actually... no.

Jesus, this is the OLDEST Internet rumor that has yet to die off. It's damn near "640k should be enough for anyone" in legend.

Please read this this and get educated.
