Re: Here we go agains, Another PSP games exploit i found

Maybe it's just that I'm blind but, did anyone notice that he doesn't have installed any PSP game on his Vita?

Re: HBL - Compile Errors

Anyways, I don't have enough time to deal with this stuff anymore... If someone trustable wants the name, manipulated savegame and the exploits folder for HBL of the game, go ahead and write me a PM. (Working HBL will not be provided.)

I appreciate the help I got from you guys!

Re: I found two bugs in different PSP games

Most likely they won't lead to an exploit. Its a good sign if you can get full control over $ra, which is aparently not the case here actually you can exploit without control over $ra too, by just taking control over EPC (for instance with jalr-like instructions) such bugs may very well lead to exp...

Re: HBL - Compile Errors

Looks like your game does not import such calls. What does the Ruby script tell you about this? I assume you're talking about the gen_exploit_config.rb script... Here's the output: [spoiler]can't find address for UID 0x04CB6A73 can't find address for UID 0x046A2D73 can't find address for UID 0x046A...

If you have no experience in programming or understand how the MIPS architecture works you should quit on those crashes.

But keep looking for others!

Re: HBL - Compile Errors

The error is because the linker cannot find those functions, and thus you're not linking the PSPSDK in your project. How are you compiling it, as what command(s) are you running? PS: also compiling is not programming, moving to correct forum. I'm trying to compile HBL for an exploit I found. I did ...

Re: Any Way we the community can help test for xploits?

As far as I am aware you have to be pretty good with asm to perform a successful buffer overflow to point to your executable code. Also what happens if the buffer is not big enough for the exploit with a computer you can point to another place in memory does it work like this on the psp? I know the...
