Sorry if that doesn't help =/ I'm not a programmer, lol.

Well there could be several ways as to how Sony signs the PSP eboots. Think of the PSX games. Any can be bought from the PSN store and they work on both the PS3 and PSP (i think, don't own ps3). Maybe there is a shared key between PSX games and PSP games which could also mean they sign both the same way? During the presentation at that hacking conference, they showed the structure of a PS3 app. Perhaps PSP also has a similar structure and that they also sign the keys the same way (random number is constant for each) which in this case, all you have to do is a math formula with 2 PSP signatures to be able to solve for the private key.

Ok, thanks guys, will have a look.jigsaw wrote:Standard ELF, isn't it? Does objdump work?hmmm, so now I guess that from this ELF, I need to start decompiling stuff... any existing tool for that?
Actually, why not... I hate to reinvent the wheel, but it seems to me right now that nothing as convenient as prxtool exists for the PS3 yet. this would be an interesting project.m0skit0 wrote:I don't think you need 500$ to disassemble IBM Cell assembly. There should be some disassemblers already available out there. Another option is writing your own disassembler (but I guess this doesn't even interest you )
Ah. Well I suppose the best you can do is use documentation and your experience.Wololo wrote:MaX_SLayeR: I think I already have the tools I need... unless I can find a decompiler somewhere.
Regarding contacting other devs... well I think in the scene it's all a matter of trust. I know I can freely ask questions here because we know each other, but as far as the PS3 is concerned, I'm a nobody. I don't think anybody in the PS3 scene will answer my questions if I don't have something to show. At least that's how it works on the PSP side... people who don't already have 90% of the answers won't get a reply to their question (the principle being: 90% of your questions can be answered by google and a bit of personal research, so show us that you did your homework...)

I think you're doing the same mistake I did. you're running key 3.15 on firmware 3.55, or something similar. Be sure to use the appkey matching the PS3 update you used.JJS wrote:the iso key seems to kinda work, except that I get an empty output. But decrypt-self shows the file informations, so I guess the key is correct.
