/g/ is fail

I was looking into modding my psp, and custom firmware's caught my attention. Now, I know building one from scratch is out of the question for a newb, but I wouldn't mind taking a gander and altering to some extent. I have some questions tho...

1) Wikipedia states the PSP(amongst various other consoles) uses a system based on the old RISC computers. Does this mean i can use mips assembly programming for RISC comps? Is that the language these firmware are written in, or...?

2) What hardware/software would i need to import/export the firmware from/to my PSP, and then read/edit? Can I use the handily built-in USB port, or do have to do some soldering/general arsing about?

3) Is there any resources or documents detailing these processes,Information found/discovered, or common hacks used?

I KNOW dark Alex had already made some, but I'd like to take a shot at it.....

tl;dr - how do i programmed PSP?

>>18
Waitaminute, whats wrong with >>15?

>>9 claimed that MIPS = RISC. >>15 said that, for that to be true, every element in MIPS must be in RISC. >>15 then gave an example of a element in one not in the other, making the equality false...

You, on the other hand, attempted to prove that a set of even numbers was a subset of the naturals, then tried to prove it false by testing a number in the naturals not in the set of evens -- which is OK, but you assumed that E = N, not E subset N, and proved E != N.

>>15 is talking equalities, which says that each must be a subset of the other... you are not. By showing an element in one and not the other, it proves an equality does not exist.

Therefore, >>15 may be dumb, but is correct... >>18 makes an obvious fallacy and is a tool.
