How Was Overflow Created?
« on: July 21, 2006, 08:47:00 PM »
There was a file called overflow.gif(im not sure if it was .gif but I think it was) and it was used so PSP V2.0 people could put that picture on there PSP and try to go to it and it would like mess up their PSP and it would sota like break. It would overflow the PSP and it would tell you to press circle to reset your PSP and it would make it reset to V1.5 so you could put on howbrew. Does anyone know how the overflow.gif was created. I wanted to know because I was thinking I might be able to find a way to make it overflow more or something so V2.X people could go to 1.5 for homebrew.

you cant just make it overflow more.... its pretty straightforward how it was done provided you have background in buffer overflow exploits

The bug in the tif handling of the PSP allowed custom code to be loaded when that special image caused a buffer overflow. Look up a buffer overflow on google or wikipedia.
