It is sort of baffling why anyone would need to mod a PSP in order to have two analog nubs. Why isn't one enough? Is playing Me & My Katamari just that difficult? Or maybe there is some sort of massage therapy simulation game out there that requires the most accurate symmetrical touch scheme? Perhaps a Karate Kid game -- wax on with the left nub and wax off with the right nub. Well, whether it's useful or not, someone still made it.
LordNico of AcidMods made this slim dual analog stick PSP. The second analog nub replicates the functions of the regular four-buttoned pad. While it's a neat trick to pull off, it's something completely unnecessary. We suggest just to check out the dual nubs in action in the clip after the break and not try it yourself.
