Developer shevens, from ps3crunch has found a way to boot PlayStation 1 (PSX) backups on his PS3 slim running custom firmware v3.55–Rebug v3.55.2 to be exact. He’s not sure whether this method will work for jailbroken PS3 consoles with firmware v3.41. It’s important to note that saving to memory card does not work.

hi there,

I am ScHeVeNs a German PS3 Developer,

I have found a way, to boot any burned PS1 Backup Game, its not very hard to make…

Requirements:

PS3 with 3.55CFW
(maybe also a 3.41 machine, but not tested in moment!) ( I use Rebug 3.55.2 for that )
multiMAN latest version!
PS1 Backup on burned Disk

……

Start your PS3,
Insert your burned PS1 Copy,
start multiMAN,
go to filemanager mode,
search for:
dev_flash\ps1emu,
Press X on ps1_emu.self

Tada, your Ps1 Backup will now boot and you see the PSLogo Bootscreen.

maybe this works also on PS2 Games Backups but i have a PS3 slim….and can not test this!

Have fun with this….

And give $ony a slap in her ….. face.

If you’re having problems, here are some additional information that may come in handy.

i use rebug 3.55.2 the main pup not the latest update…

and OtherOS++ Patch not more….

i have tested this with many games and all works…

FF9,
RE3
RE2 Leon Disc

and the old but good XploderCD9000 this also works with cheats enabled….

on Final 9 or RE3….

try the netemu.self with the burned disc inside….

hope this fix your problem.

Update: One of our readers has decided to share with us a method on how to save your PSX game progress:

I <3 Sony says:

****HOW TO SAVE PS1 GAMES****
Create a PS1 memory card under Memory Card Utility (PS/PS2) and set it to Slot 1. Now, multiMAN will be able to access and save to this slot.

Note: Be sure to NOT run multiMAN before creating Slot 1 or it may not work.
