Is it possible? PSPLINK only seems to offer instruction breakpoints.

After some research I found out the brown wire is for mic input but is this safe? I'm concerned about the added power from the audio source.

I was thinking that it would be easy and cool to combine headphones, the remote cable, and an audio cable together so I could send audio directly to the PSP for say, online games and skype. Do you think this would be dangerous at all? And does anyone have a I/O map of the remote plug?

Is there any way to dump the memory in a game or homebrew? Perhaps to the memory card or USB flash drive?

Remotejoy ftw

So there is no way to access the CPU L1 cache in usermode?

After reading up about the PSP, I was wondering if the data cache and the instruction cache really the Scratchpad? Is it accessable in user mode? Also, what is the difference between cached and uncached memory (ex. 0x08800000 vs 0x48800000)? I would guess that the cached area checks to see if it has...

Alright. Everytime I try to access it (using assembly) I freeze. Probably since I am trying to use it with a UMD game, not my own homebrew (I do have UMD Cache on ofcourse). But thanks for the info anyway :).

I'm trying to see if I can use the PSP's extra RAM in user mode for assembly code. I know that the normal the range of the user memory is 0x08800000-0x0A000000, but I don't know where the extra ram area starts or if I could even jump to it. Anyone know?
