Deank isn't the "keymaster". He does multiman as a hobby (that obviously he loves as do many others) he is pretty well known because of this even if he had the keys it would be a very bad idea for HIM to release them, plus he got rid of LV2 and BDEMU built in because of such legal things.
Patience, NORMALLY you wouldnt be able to do any of this (backing up etc) ive played video games for 26 years so back when atari, nes, commodore 64, intellivision etc was out you couldnt backup games at all (much less be able to complain about it via internet). Now you can run these old consoles on the ps3 and backup ps3 games, so quit whining and let him do what he does develop multiman.
