PSX Emu on the PSP, Possible or Not ?

I think the PS1 can be emulated on PSP better than PS2 does. The PSP CPU should be nearly binary compatable with PS1's. I can't see why sound would be a problem, and athough PS1 and PSP have the same amount of Vram, the PSP GPU's 5.3GB/s bus should keep it from being a problem.

and saying PSP can't run ps1 because it can't play Snes full speed is flawed logic. the hackers haven't found out how to fully utilize the gpu yet. that's probably why even though genesis had a faster cpu then snes did, genesis runs faster(snes has a better gpu than genesis) once hackers figure out the gpu, everything will be faster. hey GBA can emulate snes, don't tell me psp can't.

and as for weither to port or code from scratch, I say code from scratch. ps1 emu's on the pc aren't even 100% perfect. and coding from scratch eliminates design flaws that might cause problems if you ported one.

GBA runs snes at about 20% speed first off. I was saying snes is 4mhz where is psx is 32mhz. Its a good comparsion. No amature coder has the skills to do it. PSX on Xbox took tons of effort and just has enough power to emulate psx perfectly around 55 to 60 fps. PSX emulation on psp will never be better than crappy.

Have you seen some of the homebrew thats out there now?
I mean come on this stuuf is from exsperienced coders, you dont get results like uosens9x v.27 from an amature. Just because these people arent pushing out code for sony or microsoft doesnt make them (amature) You know these coders do a lot of there work in smal groups if there is any more then just the single coder. while on the other hand it takes a crew of about 20+ people to make mario blow sunshine up your ass. These homebrew developers. Could code circles around some of the people you (wouldnt) call an amiture!

My point is Give these people the respect they deserve.

In fact. did you know that when the pc version of final fantasy seven was comeing out squaresoft was so short handed. they hired sevral homebrew developers to help finish it. (Homebrew Developers) This is actuelly acommon pratice amoung hugh software development companys. Think about this..
If you where running a software development company. And where pressed for time and money. would you hire the ivy leauge collage guys that cost a whole helluva lot more just cause they have (papers that claim there not an amature- Meaning in most cases they paied there way through collage) or would you hire a a team with the skill to get it done. the list could go on but rerto studios. The mertiod prim guys?? Yeah Got there Start in Homebrew.
The lesson Here is respect Skill..

The debate rages on...
If your going to use processor speed to justify emulation speculation(say that 5 times fast), look at it this way:
Dreamcast ran some PSX games with bleemcast perfectly, and the PSP has a faster processor.

I say instead of debating whats possible, we debate what will actually come to fruition.

Someone was wondering about memstick prices...Dont worry, Xecuter has got a solution that involes usb hhds and flash memory adapters

Well a 1GB stick is perfect for PSX games, you wouldn't need all the discs of FF7 on the memory stick at once you know.. a 512MB would fit most games actually.

I think it would be possible, but the emulator would have to be coded from the ground up, so I doubt it'll be coming anytime soon.

PSX is possible. As mentioned eariler, the pocket pc emualtion came a long way with the PSX. Check out this link to their web site below. They were able to make very small ISO's of the discs.

Never say something can't be done, because without dreams whats left. That is why most of us visit sites like this daily. We are waiting for someone to amaze us, or show us something that CAN'T be done...

I love it how people always say "coded from ground up" as if that is the holy grail of console emulation. Here's a little no-so-secret piece of info you should all know about bleemcast: the only reason it was coded in 100% asm is because that is what rand codes in.

Every single thing he has ever done has been 100% asm, he doesn't work any other way, and is most comfortable writing assembly for whatever machine rather than C or C++ or whatever else.

Around 90% of all code in an emulator (excluding processor emulation) cannot be made to be any faster simply by writing it in asm. There are two very important things to do in order to make a port as fast as possible (as fast as noticably possible): writing CPU emulators that are in one way or another optimized for the target processor (wether or not it's in asm) and writing A/V outputs that utilize the A/V hardware of the target console.

Im very interested to see a few programs you have coded or projects you have worked on. Im very interested, you seem like one suave mofo quzar. and from one artiest to another I want to see some of your work.

Ps you dont want to see mine. as I am not a coder. Nor do I know how to code very well I can however whip you up a bmp to jpeg conveter :P

"shadowprophet" Cause he wants to see the goods

When I say "Ground up" I mean written with the PSP in mind from the start, and not a port of a PC emu...

Are there even emulators for the Sega Saturn or Nintendo 64? I mean we should be taking each generation at a time...cause someone posted that the SNES games need to be overclocked to run decently...how can we ever expect PS games to run anything over bare minimal.

Is there even an N64 emulator that exsists and works at all? I've not seen one...getting a good emulator whether it's ported or ground up from scratch will be beyond hard.

I remember the Bleemcast, it wasn't exactly the greatest emulator ever...it worked but it seemed slow and something was lacking in the graphics.

Time will tell about a PS emulator.
