Why Groove doesn't like PS2 Discs...?
Why Groove doesn't like PS2 Discs...? –
So I was curious about why we haven't had any sort of PS2 HD loader for at least us few people with built in PS2 support. I thought maybe it's because PS3 games are mounted with the BD Emulator and maybe if you were to add a PS2 disc to that BD Emulator, it would run it as a PS3 game (which just wouldn't work obviously.) So I thought I'd do a small test:
I was going to load into jailbreak. Put in a PS2 disc. And see how the PS3 mounts it. (dev_bddvd, dev_hdd0, etc etc)
When I put in the disc... nothing. The disc didn't show up on the game list. I made sure it wasn't my disc. I booted into the ps3 like normal and the disc shows up: Playstation 2 Format Disc.
So my question is... why does the payload block PS2 access for models with PS2 support? Does anyone know?
Found that thread just as you were posting it XD
So the PS3 restarts when you press X on the disc correct? So if you had an app that did this by itself with a burnt disc... Could that work? How does the ps3 start to load the PS2 disc? Does it just detect that is IS a PS2 disc and send a special restart command to the PS3? Could we find this command and send it to the PS3 from an app? If it does the disc check before you restart and not after you restart you would be able to load burnt discs... better than nothing?
I'm assuming you couldn't just
the elf from the disc...?
Well, for PS2 games it boots into the PS2 hardware/emu, and when you quit the game it boots back to PS3 in normal non-jailbroke mode. I think it should be possible to create some kind of virtual swap switch, if you can block the disc eject/insert notifications (syscall?).
It would probably make more sense to attempt to do this for PS1 first as it's all software emulation and doesn't break the exploit.
Sorry, I'm not a dev, but this may be helpful;

I just figured out something interesting, when you quit the ps2 emulator, instead of restarting lv2 all over, it just switches back to lpar2
Are the PS2 Memory card images on the PS3 encrypted? Could we alter them, put the PS2 Free McBoot/Independence exploit on them, and do things that way?
That won't work unfortunately.
Well PS discs, according to my ftp program, mount at:
dev_ps2disc1 (I assume this is for ps1 games?)
If we could get the payload to at least recognize and mount real ps discs... maybe you could make an app that redirects something off the hard drive to this. Could work for PS1 games at least.
For PS2 discs... you could insert a burnt disc, load an app, have that app remount the dev_ps2disc to some fake image on the HD. Then when you're on the Main menu, it'll show a PS2 format disc. When you click it, the system resets and loads whats in the disc drive instead (assuming it doesn't check the disc on restart too).
