Hi there,
I need help from some assembler guys. I just programmed intel and a little bit m68k so far, and I just need a few bytes...
Assume the following environment:
The psp executes a thread (unknown mode) and the instruction pointer runs straight into a memory region that I can feed (yes, exploit style).
Now what sort of code could I place there to see a reaction of the psp? Really just something to see that the pice of code was executed. Like a black spot, a reboot (not from crash) or an exit. I thought maybe calling sceKernelExitGame() should bring me back home, but I don't understand how the libraries are being called. You have the ID, and then?
Or even better, is there a predefined memory region for the graphic buffer (like the old intel days)? Also, where can I find a list of instructions + opcodes for the psp cpu?
Thanx alot!

I should think there's enough in svn.pspdev.org to get you started?Snk wrote:Hi there,
