January 27, 2010 // 12:34 pm - I just started to take a look at Folding@Home / Life with PlayStation as part of my PS3 research. There are several little details which are pretty interesting...

One thing which got me interested, is that the "game" has more permissions than any other game or application. Normal games do not have access to the root of /dev_hdd0/ but F@H has.

It can read, write and execute which was found out as it creates a folder called /cntlnk/ in /dev_hdd0/.

There it caches several music files you play while running the application. This is handled via a SQL Lite Format 3 DB (db1.1.sqlite) in /NPIA00002/USRDIR/data/wlop/.

Another thing is, that F@H/LWP can override the PARAM.SFO. Normally the option window when u press triangle in XMB on a game just reads the data, PARAM.SFO passes to it.

But here, the automatic start option is not loaded via the .sfo. It seems it comes from an external XML file in the game directory.

The last I want to write about now is, that older F@H versions were able to control the SPU's partly. For example it was possible to define how many SPU's are used at all.

These are just some points that came up so far. I will keep you updated when there is more!

I don't know if this could be useful, but probably i've founded another bug in folding@home that freeze the ps3. This is my configuration:

- Ps3 slim 120 gb
- Firmware: 3.01 (this could be the real problem)
- Folding@home: 1.21

Every time i start folding@home it says me to wait because it's preparing to download... But after minutes it doesn't download anything and the progress bar is still stopped... so I exit the game, but the ps3 hangs up for 2-3 seconds and then restart himself.

This problem occur everytime i start folding@home... I hope could be usefull to you (also if I think no... XD)

I think that the probem is that I'm still using 3.01 firmware with a recent version of folding@home. Probably new firmware add some function that folding@home uses...

If you want I can upload a video that explain everything better...

Sorry for my English... I'm Italian...

Good finding. I think F@H is a serious flaw for the PS3 ... first we were able to install PS3 downloads with a hacked link and now this

Yes but in linux only 6 SPU's, with the exploit we can, actually use 8 thats correct.
