i dunno... Id be kinda weery of exposing it to warm climates thus causing possible condensation inside the machine, if you have to, let it sit for maybe like 12 hours or a whole day to dry up if condensation is extreme
it would probably freeze and mess up the internal memory cuz i left my 512mb memory card in cold weather in my car once and it wouldnt work after that so i wouldnt risk it if i were you
(p.s. i just realized this is my 300th post:cornut: )
The condensation would be taken care by the Wii being heated up (on) and then the humidity being blown out by the internal fan. I still say its risky though.
