^^ it shouldnt be hard really.. like that video is just a replacement umd door and a light... light would be the hardest part because your gonna either have to splice wires together (which is what id do) or solder the wire to a board somewhere... im lazy and don't care if the light blinks to the sound like some of the mods i see so that's why id just slice into a power feed wire so i just stays lit when the psp is on... most likely uses a cheap little 5v led light.. the door will either be a replacement or you have to put the window in the one you have and that i don't know about...  i could never mod plastic like that without a ton of super glue and it looking like poo poo.. not to mention super glue melts plastic if your not careful
