| A PSP firmware 2.0 buffer overflow exploit has been confirmed in the
past few days. It means that homebrew running from the memory stick
with a firmware 2.0 PSP is not too far off. This is good news
considering there are already homebrew SNES, NES, N64, GBA, MAME, Doom,
Genesis, Gamegear, Dreamcast, Atari ST, Amiga, Neo Geo, PS1, Spectrum,
and Wonderswan emulators among others. In the last day or so, it has
become possible to run some binary code with this exploit:
Pure binary loader.
* it's loaded at 0x08810000
* it's max 64 kb
* it's pure binary MIPS code
* you have to use syscalls and not NIDs
* it runs in user space!
* it's called h.bin (paint screen blue yay!) in the root of the
MemoryStick
Set the frame_buffer.png as background like before and Place the new
overflow.tif in the photos dir and the h.bin on the memory stick. It
loads ms0:/h.bin
