Sadly, this is all most impossible because of two reasons dealling with the processor:

• The PSP uses a MIPS style proccessor. Although this is the smaller of the problems, the kernel code still needs to be tweaked sometimes, and so do any apps that you want to run. You'd have to download the scorce and recompile everything that you wanted to run. Not to mention that the MIPS CPU has a reduced instrution set, meaning that some operations are not supported or take longer to complete.
• More importiantly, the PSP does not have a MMU (Memory Management Unit). This chip handles what processes are running in memory, pages, swaps, and locates them and whatnots. Because the PSP lacks this, it has to be compensated for in the kernel (Hard, but there are versions of Linux that don't need an MMU, though they are slowed down because of it) or emulated.

In the end, it is a lot easier to port individual apps then to port whole operating systems. A good example of this is the Links2 browser. It is a Linux browser that has been complied for the PSP (with changes, of course). But the code is still mostly the same.

ah, then I guess that's why the bochs emulator runs so slowly?

well, what about my other idea for adding usb support?

like say, adding support for one of the mini keyboards they make for pdas, cellphones and etc. either in the ported app itself or as a plugin for the custom firmware....


Oh wait, is the usb port on the psp a standard one used in portable devices or is it a custom port used only in the psp?

it's a standard port. but it's not the one used in keybards and stuff. but i think adapters are available

lol, there it is!

will probably be a while before it'll be able to do anything usefull though
