Playstation Emulator (Psxxx) for PSP Announced

[mat_dizzy]

LOL ooh i'd love to see that actually happen

I can say that I have suspisions about this emulator. I don't want to, but take a look at the technical side. An ISO of a PS1 game is, take the guts of 400MB. Obviously this cannot be all loaded into ram at one time, seeing as there is only 24MB of actual user memory. Secondly, there needs to be room left for recompilation/interpretation of the game's code. N64 games are a lot smaller in size (SM64 is only 10MB) so they can easily be loaded into memory.

I really hope this is a work in progress, my entire street are terribly fond of the early PS1/late SNES FF games and they will all be out to buy PSPs if this emu goes anywhere.

You got the idea wrong. Since the Ps1 is Disc based, you dont have to load everything into ram. The data will be accessed from the ISO on request. Its exactly how ps1 emu work on any system. Ps1 also does not have a lot of ram.

i was waiting for someone to mention that.

(by the way, thanks for the pm monkey, i had a good one, make sure sniper doesnt hate me...haha)

We need competition in the PS1 emu development area! I sure hope this is real.

Like all other good Emulators for PSP, we need amother person working on 1 and trying to make a better emu.

It seems if he dosen't know the difference between a ISO and a ROM than this will most likely turn out to be a fake, but if it turns out to be real then this guy has my deepest respect. My PC with epsxe can barely play FFVII smoothly!

That would be Sony...

Thought so...

Also I was just looking up the differences between PS1 and PSP:

PS1
CPU: 33.8688 MHz
Main RAM: 2 MB
Video RAM: 1 MB
Sound RAM: 512 kB
CD Speed: Originally 1X, later 2X -- maximum throughput = 300 kB/s

PSP
CPU: 333 MHz
Main RAM: 32 MB (8 MB reserved for kernel)
Video RAM: 2 MB

So I don't think it would be completely impossible for someone to make a prety decent emulator eventually.
Atleast Sony's one should work great.

What is the name of the creator?? cause if its Timboman,Zx-81 then it might be possible or even a unknown coder thats rocks?

ah sry i understand 0 of this but, if the ps1 cpu as 338688mhz its impossible for a psp to emulate it or is it 38,8688mhz

p.s - can some1 explain me what are frames per second (FPS)
