I can finally post! I've mainly just been lurking this thread (and the preceding one) so I have no idea if someone elsewhere on GAF has the same avatar I'm using. If so, let me know. I have some backups prepared.
Anyway, I've been wondering something. The GameCube apparently consumes 23W, while the Wii was able to be reduced to 18W even with bluetooth/wifi, more RAM, and increased clocks for the CPU and GPU. How much further could this be reduced within reasonable costs? Would 10W or less be feasible? Could such components be put in the apparently lightweight U controller (suggesting a modest or nonexistent heatsink) without fear of getting cooked?
It would free up precious space in the base console to help maximize the new components, and make the controller a bit more capable itself. I don't seem to remember this being discussed yet, but sorry if it has.
To maintain perfect backwards compatibility in Wii mode, the Wii components would operate without knowing any of the new components exist. An independently operating portion of the controller would tranparently route the Wii AV output to the controller screen, as well as stream it to the console to be displayed on the TV. (We know the controller is capable of streaming audio and video back to the console since video chat has been demonstrated.) Assuming the base console streams well above 63 Mbit/s reliably, it should be capable of streaming the data being read from a Wii disc to the controller. The controller transparently passes the data to the Wii components.
etc...?
The added complexity of this BC implementation might not be worth it in the end though -- that is, even if it was feasible. Which it probably isn't. So... cool story bro?
Sorry to say, the project is Cubivore 2.
I'm going to be honest... that would actually make me squeal with delight.
