A korean hacker has probably made the first step of running own code on the firmware 2.00 of the PSP.
He has found a bufferoverflow in the bookmarks of the 2.00 internet browser.
Here is a link to this: http://www.psphacks.net/forums/viewtopic.php?t=5208
I'm not a hacker or coder, but maybe here are some people, who can use this information, as I did not find any similar topic in this forum here.
as replied in that topic, it doesnt work for all psp's (2.00), maybe some1 could carry it further, nice discovery ;)
I personally would like to try that out, too, but I still have a PSP 1.50 and don't want to upgrade until the downgrader is out (...if it will come out at all).
Duh, I predicted this a while ago :D

wow, you genious, you predicted something predictable.
praise be to the original founder of the buffer overflow!
Of course the credit is entirely his. Hopefully they can dump the v2.0 firmware with this overflow - after that all you should need is some in-memory patching.
