PS1 Loader

[kevstah2004]

Can people try this out please "newbies not allowed "
Put PLAYSTATION.CNF & PSX.EXE onto a blank ps1 memory card in slot1 with ULaunch then place an original ps1 game into the tray reboot the ps2 an load either PS1DRV_v1.1_Packed.ELF or PS1DRV_v1.1.ELF with ULaunch or FreeMcBoot's button launcher.
Thanks! go out to Shendo of ngemu if this works!

I ran that ps1drv through a hex editor and it looks like one ripped from a ps2 bios. I'm sorry but you can't link to them either in the open forums.

I'll just post instructions on how to do it the future then, for some reason it still starts the ps1 disc in the normal manner the only reason I said to keep a original ps1 disc in the tray was to pass the disc checks.
The PS1DRV I uploaded was from SCPH-50004 which is either V9 or V10 the one with ps1 swap disc trick capability. I'm yet to see a PS1DRV above v.1.1 the highest BIOS I have is SCPH-70004 V12 if anybody has one of these http://www.scei.co.jp/corporate/release/071106ae.html let me know what it says under the system information tab.

Update: I was looking at TITLE.DB you know it has this entry to load ELF files with PS1 exploit
mc0:/BRDATA-SYSTEM/BOOT.ELF
can that be changed to
mc0:/PS1/-PLAYSTATION--.EXE
to boot an PS1 executable instead?
or would changing the entries in PS1DRV
mc0:/BEDATA-SYSTEM/TITLE.DB
mc1:/BEDATA-SYSTEM/TITLE.DB
to
mc0:/-PS1--/PLAYSTATION.EXE
mc1:/-PS1--/PLAYSTATION.EXE
work?

Never tried to change that path, but the effect would be same than trying to launch it from uLE for example. And besides i think the modified title.db have'nt been designed to boot .exe.

How would you swap in the PS1 backup, if your using a retail PS1 disc to boot it? It boots in a few secs and you wouldnt have time to put in any backup disc in that short of time i think.

What the point of this?

AFAIK, an extracted PS1DRV from a v9+bios allows you to launch a PS1 Original on every versions. With a little hack it even allows you to launch backups on v9+ without a swap trick (doesn't work on a V8- though). And no need to put anything in the memcard except the PS1DRV.

(everything is explained in this topic : http://www.exploitstation.com/smf/in...p?topic=4280.0 )

Does this allows to do anything else?

If you were to code a time delay, it might be possible, since its still in PS1 mode, but i dont know anything about the PS1 structure, so im just guessing.

In the link i put, they explain it's very hard to do thing like this as by going to PS1 mode, there is a IOP reset that clear everything out of memory, making it hard to have any progs to perform a time delay.

Apparently it would perhaps be possible but only by someone who has great knowledge of assembly and how PS2 works.

Sorry for hijacking this thread but it is kind of related:

Does anyone here know of an equivalent to CogSwapLoader for PS1 games (for older, pre-V9 PS2s)?

I was only using the PS1 original to pass the cd checks not to boot anything I was working on the principle that mc0:/BEDATA-SYSTEM/TITLE.DB could be changed to an executable file instead then that executable be able to stop the cd drive like swap magic does but in ps1 mode instead.

@remax to boot ps1 homebrew or backups on any console below v9.

non exists hence my problem and why i'm tyring to find a way around it.
I heard an original Breaker PRO disc might boot a ps1 backup though.

After reading this I wonder if using a PS1 demo disc instead of PS2 one would work.

It can't be that hard to rebuild a ps1 disc maybe do it in imgburn like you do a ps2 disc.

eg: change SSTORM.EXE with the PS1 homebrew app you wanted to load.

I wondering if any of the ps1 apps stopped the cd drive for backup swapping maybe import player, I dunno.

I use the PS1 Action Replay disc to play PS1 backups, but I have a no-solder mod (essentially the same as the card trick). However, the disc takes ages to boot up fully as it loads the cheat code database, and I need to take out the PS2 memory card as I use the same disc to launch the Independence Exploit.

So it would be good if there was a homebrew app that could be loaded from uLaunchELF via the Independence Exploit (in the same way that CogSwapLoader can be loaded), because an original PS1 disc would already be in the drive and all that would be needed is something that lets you swap in another PS1 disc and boot it.

I'm guessing that you are trying to load a PS1 import/backup without a modchip or card trick?

ok kevstah so before doing anything else, i strongly suggest to read this topic :

http://www.exploitstation.com/smf/in...p?topic=4280.0

this will avoid you to try things that have already been tried and to understand the problems you will encounter in order to suceed
