Hiya,
Is the format of the IMG file loaded by sceSifRebootIop, documented anywhere? It looks fairly simple, and I can rip out bits of it by looking for ELF headers, but that's presumably not the best solution.
Presumably in principle I can extract the IMG to a number of IRXes? ... unless I'm completely barking up the wrong tree that is.
IOP IMG Format
Yes it is (kinda) and there is even a tool to extract it, though if you cannot find that yourself then I am not going to tell you where it is. The answer might be closer than you think.
At any rate I cannot really think of much reason to extract files from .IMGs anyway other than for piracy stuff, we don't concern ourselves with anything which isn't in the BIOS for the most part so not alot of point reversing the latest sony libs.

Ok thanks for the somewhat cryptic answer... I'm sure I'm just being thick - I'll get there.
Actually I'm trying to take apart the IMG loaded by the RTE to learn more about how it works, I hadn't even considered that it might be useful for nefarious purposes until you mentioned it! There's nothing wrong with disassembling that, surely?
Edit: ok, got it. Thanks.

No I guess not but all modules in the .imgs for the RTE are also separate on the disc as well and the only ones of interest are dmarelay.irx and intrelay.irx, at least I think that is what they were called. And if you want to see how they work take a gander at TGE at cvs.ps2dev.org that has full re-written version of the irxes, at least as far as they might work :)
