Version 0.2.7:

  • Added local NP license handling.
  • Added option to override klicensee.
  • Added option to disable section skipping (in SELF generation).

Regarding the PS3 SCETool Scripts (linked above): This is a nice little set of batch scripts that someone made to work along side SCETool.

Use the GETSELFINFO.bat to figure out what version your EBOOT (my copy of Resistance 3 was ver. 3.65) is which helped explain why some EBOOTs couldn't be modified. Don't forget to grab the Conent ID if you're changing the EBOOT from an update.

Finally, in related news keperfear has made a [Register or Login to view links] stating that you will need to have at least .Net 3.0 Framework installed to use it.

Here is a follow-up from his blog today as well for those following: nwert.wordpress.com/2011/11/29/about-spu-channels-64-72-and-73/

If you are reversing the PS3′s isolated SPU modules, you will eventually notice channels 64, 72 and 73. Here are some C functions, that roughly describe how they work:

It seems that lv1ldr is storing it’s version into a special storage area.

And e.g. isoldr reads the version from the storage area and compares it to it’s own version. If the check fails, isoldr will just stop execution.

I wonder what else is stored in the area and how long the data in it persists, so my next idea is to code an isolated elf, that allows me to specify the value written to channel 64 and then dumps the data from channel 73.

Yep. WE mortals don't do nothing with this stuff. But i suppose it's an advancement about a free solution...

Oh, some news: And no, I won't release eidtool. If you want the algorithms, you'll have to start reversing

Cool, we can close this chapter too
