PSOne Emulator for PSP
 

I was wondering if someone knew how to go about it. I am not sure if mine can play PSOne games already. I saw some software that can do it but I'm not sure how to go about it.

Specs
System Software: 3.71 M33-2
Slim and Lite

It's easy to do, it works well with a large number of games, and it is well worthwhile. It only takes a while to learn how to convert your games. Once you've done it the first couple of times it should become second nature. The biggest problem for me is memory stick space.

That site has a few guides. There's a tiny bit of outdated information there, but if you ignore the references to specific firmware it should work. If you need more indepth informatin about the latest tools and whatever, try the MaxConsole Forums.

To answer your question, your PSP can already play PS1 games. Sony included a PS1 emulator in the firmware a long time ago, for games downloaded from the PSN store. The scene simply learned how to use it for any game. I wish they'd hurry up and do the same trick for running PS1 ISOs on the PS3.

@Soluzar: Thanks bunch...so I don't have to install anything anymore? I just need some ISOs??? Are there exceptions?

Basically, you take an iso/cd of the game, and then convert that into a set of files. YOu copy those files onto your PSP.

^-^ has a really good guide on this. Check it out.

You don't need to install anything on your PSP, but you don't just use the ISO. That site I linked to has the instructions to convert your ISO into what the format compatible with the PSP.

There are some exceptions... not every game works, but a lot of them do. Some games work better on the emulator from a particular firmware version. There is a program called POPS Loader which allows you to load the emulator from a different version of the firmware. POPS is Sony's name for the emulator.

You'll find a summary of what games are compatible on Maxconsole, and a more detailed list is available
here. Games with more than one disc can be a problem... but there are ways to get around that. Games which require the right analogue stick just aren't playable. Games which require all four shoulder buttons are a little bit difficult too.

download PSX2PSP v1.2 - Popstation GUI to convert iso games to bpb,is too easy.will make folder for game,than put it in

m:\psp\game\

OK I think I got it.

Thanks

EDIT:
Oh yeah...Now I need a better ISO of xenogears...my CD is um...overused...cracks galore

Is this "real" emulation or is the CPU inside the PSP compatible with the instruction set of the original PSX?

is cpu are compatible to play psx.

Min: Make an iso of the game with Isobuster, then mount it with Daemon Tools, then go through the steps.

The CPU is from the same 'family' as that of the PS1, so that probably helps. I know the PS1 CPU was called an R3000 processor, and I think that the PSP CPU is called an R4000 as though it is just an upgraded version.

That's surprising. PS1 CDs seem relatively tough, to me.

I assume however that the GTE and SPU are in fact emulated, because I don't seem to find shrinked versions of that chips on the PSP.
@RYU: Any details on this matter? I see that both main CPU are MIPS-based, the PSX one is a R3000A and the on on the PSP seems to be 32R2.

Additional Spam:
It's definitely not a R4000, which can be clocked at a maximum speed of 100MHz. AFAIK the PSP main CPU can be clocked at rates at bit above 300MHz, when using homebrew firmware.
Compatibility howerver should remain as the MIPS instr set didn't change so much over time (same as the x86 one).

@LiquidAcid

PlayStation:CPU,Custom MIPS R3000 at 33.8688 MHz

PSP:CPU,32-bit MIPS32 R4000-based but from R3000,Floating Point Unit, and a Vector Floating Point Unit,secondary CPU present in the Media Engine is functionally equivalent to the primary CPU save for a lack of a VPU. The MIPS CPU cores are globally clocked between 1 and 333 MHz.32R2 is is old and eliminate it.R4000 alone maximum speed of 100MHz,that why see R4000 addon to max speed to 333MHz.also that why can play psx from cpu.

Indeed I was more interested about the details of the GTE emulation on the PSP hardware. At least there binary translation (dynarec) is needed, because you can't virtualize the existing hardware (or can you?).

Wikipedia fails again, I see.

uhm..lets just say my CD is not um....the normal kind :D. To actually last more than 1 year is rare for this kind of CD...but this lasted around 8 years...so I can't complain. It still runs...just not the cutscenes.

Thanks again ...

Ahh. I believe I understand now. I don't think you need to be coy about it though. I don't think this forum looks down upon that kind of thing.

Really?? I must have in another forum....there was a rule that doesn't allow anyone to talk about it. Only one of my game are actually real...RE1.

I'm pretty sure this forum doesn't care what games you copy. Sad to say, some games like Xenogears are really expensive now. If you don't pirate them you won't play them. I never got myself a copy back in the day, even though I've got a whole bunch of other moderately rare RPGs from that era.

I just want to ask...is there any lagging when you play a music game on the emulator? I just played Bust a Groove 2. I just want to check if its my lack of skill or if there is a lag (like the one on the pc emulator). Also I noticed that my battery time seems shorter when I plat emulated games. Is there a way to fix these problems??

EDIT:
I was wondering if there is a way to convert epsxe saves so that you could use it on the emulator on the psp.

tell what type save file for epsxe ?

There is. You need to rename the memory card file to the ID number of the game you're playing. You know, the one that is like "SLUS_123.45" or something, and then you can use a plugin called CWCheat to import it.

You can do that no problem.

only you need CWCheat to import save .

ok thanks again guys

I know it seems a bit late but...I am having problems with the CWCheat. I've already enabled them but the CWCheat menu doesn't come out even after I press the "select". Also I was wondering. It says that I have to name the .mcr file as the game's ID. Does that mean that in one .mcr file I should only have one game saved?
