About PS3 Compatibility

**ritchan** · 10-14-2009,08:23 PM

Hello all, I'm new to this loader thing, so excuse my ignorance. So from what I know, USBLoader has been open sourced in the middle of this year, and we're at OpenUSBLD 0.4 beta already, right?

I also understand that one can't just do a straight copy of the PS2 ISO to the HDD, it has something to do with USB Advance formats, except that there are USBA versions of OpenUSBLD and there aren't. Can somebody please clear this up for me? Also is there work on a new filesystem driver for USBLD, preferably something that supports files larger than 4GB? I understand there's an ext2/3 driver for Windows.

Most importantly, does this work on a PAL PS3 60GB? I've heard lots of people saying that you need a USA PS3 60GB to do this, but

shows that somebody had got it working on a PAL PS3. I don't know how he did it, I don't think he mucked around with USBLD's source code.

0.41 and it is Open-SRC, yes.

It is possible to load ISOs, it is just not implemented since it is limited in some ways.

-FAT-Filesize-Limit
-Driver-Filesize-Limit
-...

Just god can say that, but I assume we´ll not see one because every additional FS-Support will let the driver grow.
Every more Bit/Byte of RAM it will cunsump, can make one more game incompatible...

Older versions (like 0.4) should work normal on all PS3s with BC, also those which only/mostly support PS2 by software.

Btw.: There is a stickied thread in this forum.

Hey, thanks for the quick reply. I saw the stickied thread, but it only had 0.41 and didn't mention the older versions, plus the PS3 file didn't come with a readme. Where can I download version 0.4 or 0.3 of Open USBLD?

Do you think it would be possible to have a USBLD version that supports ext2 only? It's a very simple filesystem, as I've heard.

The only version that works on the PS3 with software emulation is 0.2/0.2b (which is not open usb loader, is patched usb advance)

The Open usb loader >= 0.4 (0.3 did not come out because I just started with 0.4 which was better project) still have not got it to work in those ps3.

Apparently there is any problem with LoadModuleBuffer that don't load imgdrv in the reset.

Here is the log on the ps2:

And the same in ps3:

If anyone knows how to fix it, to tell me because I have no idea how to fix it.

Once I get my PS3 I'll start work on this, sounds interesting. Does 25/26 mean everything loaded ok or what? It looks like imgdrv itself has a problem with the software emulation. Do usbhdfsd and isofs load? If so, then imgdrv probably has a problem. If not, then the problem could be with the modules and the loader.
EDIT: been looking through the source of 0.41, there's no indication that ret=25 or ret=26 means anything.

What toolchain do I need to build this?

Instead of ret it should be id because is the id of the loaded module.

imgdrv is needed to be loaded for resetting with custom ioprp image. without it can not continue.

It must be a bug in the emulation of the EE in the ps3 because it works in both the ps2 and ps3 with the emulation by hardware.

I think any expert in ps2 would know how to fix, but I do not know.

(usb advance also uses loadmodulebuffer and it works in that ps3)

I thought you of all should know, since your name is on the patched USBLD. BTW I really doubt that's USB Advance. Sure, the tutorial here:
http://www.haxnetwork.net/showthread.php?t=8888
said to copy the files over using USBAdvance, but all the execution on the PS3 is thanks to you:

I'm downloading the ps2 toolchain. My PS3 CECHC04 works just great, my only problem is that I might spend more time on Valkyria Chronicles than this.

So if I understood this correctly, I need to use these really old versions of GCC and binutils and newlib to build something that'll run on a PS2, right? And the code that's running on the screenshots that ifcaro posted is from iopmgr.c, line 148? ifcaro, what have you tried?
