PSP homebrew question

So, having ignored any PSP firmware related things for ever (never saw the point of hacking something that is already region free), I now find out about Remote Joy Lite, which would allow me to actually play Blazblue Continuum Shift II with an arcade stick, and suddenly turn the PSP into something actually useful.

My current PSP firmware is 5.55, can I still do something to enable me to run Remote Joy Lite? A foolproof guide to changing the firmware would not be unappreciated.

edit: The PSP is a Slim&Lite (the Crisis Core/FFVII 10th anniversary edition) if the model number makes a difference.

I personally have not a clue, but I can refer you to this thread over on Eurogamer that might be helpful.

Cheers, I might as well post it there, too.

Saw your question on EG as well.

I'm unsure of the answer (things seem to change quite quickly), but if you need a Pandora Battery and a Magic Memory card - let me know as I have one you can borrow.

Thanks to 6.35 PRO-B none of that malarkey is needed nowadays.

I am on 6.37. Am I screwed?

I think there is a custom firmware for 6.37, but it's not as good as the one for 6.35.
