PS2 HDD Support & Discless ELF Launching from PS3 XMB WIP


Sponsored Links
187w ago - Here is my WIP project on PS2 HDD support and discless ELF launching from the PS3 XMB. First off I'd like to thank w1zard0f07 for being able to at least try helping me out with this one.

Over the last month or so I have been working on a little trick for the Phat Model PS3s. In summary FFXI is PS2 title that requires PS2 HDD support which is added via [Register or Login to view links] ([NPIA00001] PS2 System Files).

From there a "PS2 partition is made", which translates to an IMAGE.DAT file being made to exactly 12GB (according to GameOS/FTP this file is 0kb large)

The contents of this HDD is listed in the attached "Blank PS2 HDD.txt" (The partition list is corrupted according to w1zard0f07, quote "APA partition table on your dump file is broken")

The XMB icon is not launchable by this point, and requires the PlayOnline Viewer to be installed. This undergoes a certificate process, and then continues to install PlayOnline viewer to the "PS2 HDD." It is after this point the XMB icon is launchable, and goes straight into the PS2 mode reading from PP.SCUS-97269.1000.POLVIEWER and launching "dnasload.elf" (Unfortunately access is denied to that partition due to some sort of key being used... I haven't done any research on it)


Currently I am doing my best to replace atok100.erx (an elf file it appears) with ULaunchELF, but something is also going wrong...

Anyways, if any one wants to help, or offer help, please do! (It all compresses to 95MB if anyone is interested in the IMAGE.DAT (PM me)... but only for those genuinely interested in doing the research)

IMAGE.DAT Content (Blank)


IMAGE.DAT Content (With PlayOnline/FFXI)


NOTE: Although initially FFXI was required to do the research, I do not believe it is necessary to continue, because the param.sfo and image.dat created should be "pkg compatible", also the "CATEGORY" is "2G" btw.

Also, that if a proper PKG were created with that param.sfo and IMAGE.DAT for "SLUS20071", it would add native HDD support to "Swap Magic Coder 3.8", which is able to launch any elf it desires, including just released OPL 0.8.

Just to clarify, this is for backwards compatible PS3's 20/60 and semi 80 (If you know you know) The only PC software that was compatible with the image was PFSShell0.2a.

If someone could make me a PKG for SLUS20071 with the included PARAM.SFO, that would be awesome.

Oh and I know that so far no one has said anything like "why did it take you so long to do so little?"... but to answer the unquestioned... research on this project mostly consists of reading and writing a 12GB chunk of data 2-3 time before any progress can be measured... very time consuming... and annoying...

i will ALSO re-emphasise on this fact again. PS2 hardware is made up of 2 (obviously) common components, the CPU and GPU.

Emotion Engine is the CPU and Graphics Synthesizer is the GPU.

All gen 1 60/20 ps 3 has both CPU and GPU (like they bought a ps 3 with ps 2 console built right inside).

The 4 port usb 80gb and PAL 60gb have just the GPU and rely on CPU emulation from the PS 3 Cell processor.

You can find this self on a slim too, but i think, when the install fw, this is disabled.

Need to explore, decrypt all this 3 selfs from all platform.

not correct. there is first PS3 release (NTSC 60&20gb)with PS2 CPU+GPU - this PS3 uses hardware PS2 emulation. there is second PS3 release with (NTSC 80gb and first PAL model) PS2 GPU only - this PS3 release uses software emulation of PS2 CPU (but still uses hardware PS2 GPU) and there are all following PS3 releases without any PS2 hardware on-board.

These PS3 are NOT compatible with neither hardware nor software emulation of PS2 included in firmware.

I hope now it's clear enough.

Does this work on nonbc models or only on those that can play ps2 games?
