Well I haven't got a Wii yet and now i really want one so I can install a Wiinja chip. I take it the chance of me getting one of the new chipsets is pretty high. I read that there is a series of serial numbers to look for. Is there truth to this? What should i be looking at to ensure that my Wii can be modded? I obviously cannot disassemble the unit at the store. I don't want to get one and find out I'm stuck!
