Quick Question!

Hey guys. Ive read somewhere that you can use memory stick pro's in a psp. You need to DIY and mess around taking apart old memory stick duos and card readers, soldering required etc.
Anyway, ive watched a video of it on psphacking101.com and the guy doesnt really show you how to do it.

Does anybody know a link to a written tutorial or anything? I cant find one.

Any help much appreciated!
Cheers
