Loading PS1 games from PS2 HDD?

Is or will there be any update on this? I googled around and read that because of the way HDLoader works, this is not possible. Most forum threads on other sites are a couple of years old though.

 

There is a Homebrew-PS1 emulator for the ps2 that lets you do this, but i'm not sure how good it works, i never tried it.

 

playing ps2 game by HDD( or USB) through Network Adaptor based on changing irx modules for IOP ( CDVDMAN/CDVDFS mixed with ATAD.IRX).

the ps1 doesnt use "local driver" method, cause the code for working with cd-rom is compiled with all other libraries and it is located in different place in the each game.

my 50 cent is HW based emulation of cdvd drive of console. for example it is the psio(ps2io) in the future. it can play both ps1 ps2 games from sd/hdd/cdvd/....

 

yeah i know, but what i'm talking from is a complete SOFTWARE ps1 emulator, that makes it possible.

 

the questions are: who comlete it and how many bugs it will have.

 

I have an Emulator that I got with a PSOne SDK that I downloaded, but you needed a BIOS for it to run. I may still have it floating around on my lappy somewhere??

 

It should be nice

I'll stick to Breaker Pro + CDs

 

Or a good ol' PSX. These are dirt cheap right now. I find that my RGB modded PSX with my GBS-8220 converter delivers a better visual experience than my PStwo with component cables (with or without the help of the GBS-8220). For some reason, the graphics are a bit worst when running PSX games from a PS2 IMHO. Also, some great games aren't supported by the PS2 (Tomba and one of the ported Final Fantasy collection disc for example). The fact that you can use the same controller and video cable (except if you have component) makes it really worth it.

Get to your pawn shop and buy one for like 15$. That would be my advice.

 

PS2Guy : what y got - Emulator of PS1 for PS2? or for PC?
PSOne SDK for what? maybe we need ps2 sdk for compile emulator.

 

Huh. What in the world is that? I thought only the DVR PSX didn't output RGB.

 

It's a PSOne emulator for the PC (like most are). I had it working sort of. I just needed to find a dump of a PSOne bios (like PCSX2 does) for it to work.

 

ask Haunted360 about ps1 bios , he got a set of them in zip.

and we talking about launching ps1 games on the ps2.

 

AFAIK there is no way to run any PS2 code while the system is in PS1 mode, so there's no way to implement ODEM like with the various solutions for PS2 software. Especially since the same CPU (IOP) that generally handles that for PS2 solutions is the main CPU in PS1 mode, and as slow and RAM-starved as it is, there simply isn't any way to do it.

The only way that I know of is the emulator that richi mentions, and I haven't personally tested it, so YMMV.

 

Sorry don't like that guy. He's really annoying.

l_oliveira is the person you want to talk to, I'm pretty sure that there's not anything that he doesn't know about the Sony consoles.

 

what do you mean under "ODEM" - ps2 hardware? such like network adaptor with conected HDD?
i'm not sure but when ps2 in "ps1 mode" , EE cpu acts like GPU for emulation graphic chip. lauching PS1DRV file and and iop works like r3000 with different freq of cpu

but i'm not sure does the access to HW registers through "ssbus" con to NA+ hdd is blocked?
about SW solution i've heard only emulator as ps2 *.elf , based on source code for PC

PS2gyu: I remember MORE annoying ppl here, but i just saw bios files on his site

 

it is strange that no one here ever heard of "PS2PSXe"

its a ps1 emulator fot the ps2, which allows ps1 games to be played from the ps2-hdd, and also over network as far as i know, but it requires a special software to do that on the pc.
it has been released over 1 year ago over at PSX-Scene .

 

Well I live in Canada so I don't have a RGB capable TV. I need to pass through a GBS-8220 to convert the RGBS output of the PSX to a VGA signal. Those little chinese converter boards are very picky and since I didn't have good result from using composite video as the sync input for the GBS-8220, I had to retreive the original C-Sync signal from the CXD8561 chip as described on http://gamesx.com/wiki/doku.php?id=av:playstation_1_sync . Wired R,G,B and C-Sync to a DB-15 connector (VGA connector) and mounted it on the back of the PSX (I had to cut some of the inner metal casing to make it fit.) along with a 3.5mm audio socket.

I don't think I could get any better image quality considering my TV does not take RGB natively.

 

Oh how different than the kind of approach I'm used to.

 

ODEM = optical drive emulation, as seen in OPL/HDL/KERMIT/PS2ESDL. I don't know that anyone has ever written an EE-side ODEM, but I suppose if there's enough free EE time then it could be done somehow, but I'm still learning the PS2 and have a very long way to go. Someone like l_oliviera would be able to answer this question better.

richi: I knew about it of course, just don't have any PS1 games to try it out with I hear it's quite good nowadays, though. Is it still better with 50Hz games?

 

oh i'm sorry just noticed the bottom line in your previous comment.

i didnt tested it too
