This is a double post but I figured I'd better give an update that will be noticed seeing that this is about stuff that will be brought to the thing.
I have just realised that the Wii needs cables and a power supply to run, due to this and my bag not being bigger on the inside

the following items have been ommited, sorry for the late notice, only just started packing stuff.
360 controllers
PS3 Controller
2 of the gamecube controllers
Gran Turismo 5
Hope this hasn't disrupted anything.
p.s. The adaptor is here but I had the one ps2 controller that is the most pain in the ass thing to wire to a stick so it's just connected to a regular dualshock.
