this thread should probably be locked. If there are any updates, I am sure he will let us know.

Yeah it shouldn't be locked but it doesn't need to be bumped. Don't forget to let us know what's going on PMF! Start a dev blog or something.

Are you sure? This doesn't seem legitimate at all. Phishing to take advantage of the development scene just makes someone seem like the lowest kind of shit.

Huh? He linked his screenshot from that same site in the very first post of this thread...

Yeah its his personal email he writes at the bottom of the page, and the link isn't linked to any account on paypayl, so you donate the his real email :).

But I still wouldn't donate until I see updates! And releases.. if so and it works ok, I have saved money for this donation... and it will be BIGG :D

Hey everyone,
PacManFan here.

As stated, I've posted an info-only update and given PSPSOne a page of it's own.

At this point, I don't really have anything else to show, however, I want people to know that I haven't given up. I've been working on PSPSOne yesterday and today, and I've made some real progress. I'm on my 3rd attempt at writing a recompiler, and I think the 3rd time is the charm. I've given up on the idea of being able to "filter" out the addressing scheme, and now I'm taken a more traditional approach to writing this recompiler.

I've got the recompiler executing the bios at this point, and I'm tracking down some issues with my branch and COP functions. I think I'll have something to show soon.

The man needs money to live. If we want him working on this thing 8 hours a day, we should be paying him what he would earn if he was working a normal day at his regular job. It would be a great idea if a lot of us would give him AT LEAST $10 a month, which is hardly anything at all to us, but would make a world of difference to him as it adds up. He'd probably get the thing done in 2 months if he could afford to work on it full time, and you know we'd get so much more than $20 worth of use out of it. If it's worth it to you to be able to play your favorite classics on your PSP, I say DONATE! I'm sending the man $10 right now, and if you want to use PSPSONE anytime soon, I suggest you do the same. It's only $10 bucks! ;)

EDIT: and as you can see, PMF is still hard at work so give him some support!

Please don't solicit or ask for donations.

this is great news! this is by FAR the best emulator i was hoping for (including snes)
if you get this up and running, i will buy a 2gb memory stick just for the emu :)

oh, and if anyone is gointo donate fair enough, but you shouldnt ask for donations ;)

good luck pmf!

Maybe he should get in touch with zodttd who is making a PSX emu for the GP2X. Don't know how similar these two handhelds are regarding their architecture, but maybe there is some knowledge to share.

well i just got a 1GB card, so cant wait for this to work!

wuldstock · Post by **wuldstock** » Mon Mar 27, 2006 12:03 am

PMF will you continue to work on this even though Sony is making an official PSOne emulator for psp? i can imagine that everybody who sticks with homebrew will still want to be able to play psone games and your work will not be in vain.

ALiENiD · Post by **ALiENiD** » Mon Mar 27, 2006 4:05 am

I'm sure there will be a PSOne emulator, or someone else will write one (like me ;)). I don't have much spare time, but the minutes I do, I will spend on making FF7 to work. I've looked into dynamic recompilation and it doesn't look too hard. The problem is if there is enough MHz in the PSP to get PS1 games to run smoothly.

Itaintrite · Post by **Itaintrite** » Mon Mar 27, 2006 9:47 am

I doubt the official PSX emulator for PSP will let you create an iso of a game you own and play. Sony will probably force you to PAY to download the games to cut down on piracy. I don't want to pay extra for something I already own, would you? :/

wuldstock · Post by **wuldstock** » Mon Mar 27, 2006 11:35 am

true, then PMF and others need to keep at it! all we'll need then is 1.5 psp compatibility with PS3 and all new psp games :)

well the GP2X uses a ARM9 processor, much different from the PSP's MIPS processor, the architecture is way different. but for main speed wise i'm sure they could help each other, the fact if either are even willing to give help is another question ;) btw, the Playstation also uses MIPS so the PSP should have more success with a full speed emulator than the GP2X, but teh PSOne emu for GP2X is really advanced for how early the GP2X is in its homebrew stage.

keep up the good work.
Everybody will be happy if you complete the emulator

could it be possible for psone games to be decompiled the recompiled to run nativley on psp hard ware? the way it would run a lot more eficient. http://www.backerstreet.com/rec/rec.htm

You cannot relay neither on that decompiler nor any other.

Decompilation is a NOT COMPUTATIONAL problem, meaning that it's REALLY imposible to resolve it with computers, as imposible as reaching a temperature of absolute zero. (anyways, it can be solved partially, in some "realistic" cases as Cristina Cifuentes proved, but don't expect too much of automatized reverse engineering...)

That's why the more reliable decompilers are brains, but they are so slow...
Of course, once decompiled, the recompilation wouldn't be as easy as typing "make", as it also has to be ported to a different system than the original one.

This is not the way, you won't see people so crazy to decompile full psx games and then porting them to psp.

groepaz · Post by **groepaz** » Sun Apr 02, 2006 9:15 pm

oh yes....if you make a working decompiler that outputs more than half-accurate gibberish, please let me know :=)

It gives me a warm fuzzy feeling to see my old PSX demos/games being used as test-fodder for a PSP PSX emu. Makes me feel like I've already contributed to PSP homebrew, and I haven't even written a line of PSP code yet!

caviar · Post by **caviar** » Wed Aug 16, 2006 6:26 am

Hi all,

I just posted a link to a copyrighted PS1 BIOS, not only that but copyrighted BIOS content from a development system, which end users shouldn't have access to anyway!
Did I mention that it's copyrighted, and related to the Sony SDK, which is of course a major violation of pretty much the first rule of these forums!

[Note, not the original post, edit by jbit]

Marco_N · Post by **Marco_N** » Wed Aug 16, 2006 1:02 pm

I downloaded this file, it appears to be more of the development folder rarred up.

I stumbled on the following file in this archive:

PSPSOne\PSPONE\BIOS\SCPH1001.BIN

with the string
Sony Computer Entertainment Inc. CEX-3000/1001/1002 by K.S.

I'm not in a position to verify this, but if this is an official PSX BIOS ROM then I guess this link has to be removed as it contains copyrighted material.

groepaz · Post by **groepaz** » Wed Aug 16, 2006 1:33 pm

its not only a psx bios - its the bios of a development psx that shouldnt be in the public whatsoever :=D

Locked because nothing useful has happened in the last few pages of posts.
If you're curious about a projects status, email or PM the guy doing it, or simply wait 'til they announce something!
Also, if you're pasting links to emulator stuff, don't include copyright ROMs or BIOSes, it's a good way to get yourself, and possibly emu discussion banned completely.
