Smashing the Stack - PSP Buffer Overflow Exploits

If anyone atempting to do buffer overflow exploits on the PSP, I'd suggest taking a look at this article:

http://www.hxdef.org/knowhow/stackover.txt

It explains in great details, how a stack works, the concepts behind a buffer overflow, examples on how to write shell code, and how to bring everything together using NOPs to get to the right place in memory. It has helped me a lot with understanding the concepts talked about in the wipeout browser crash thread. Hopefully will help someone else figure out how to get our own code working in there. It is not PSP specific, but the concepts are the same.

Good luck!
