So its already March and we are about to make some people really happy, countdown for Terraonion Direct has just started. It will be before this month ends but we still don´t have a date due our website being reworked (again)
Gamecube has better video output than the Wii does, although I can understand about wanting to limit the amount of systems hooked up simultaneously, as I have 9 systems on my desk right now and it gets a bit annoying on rare occasions.
I want a GBA flash cart that can run GB + GBC games without emulation, just in case the Analogue Pocket insta-sells out before I can buy one. As far as how to deal with the switch in the GBA cart slot, I'll leave that up to your designer(s).
