Came here to read about the RVGS, registered when I saw what kevtris was up to!
My interest is mainly SNES games and I'm not rich, but a price around $200-250 definitely seems worth it. If I could make a feature request then it would be bluetooth-support so I could use my SNES30 controller (from 8bitdo). But it works via USB too. Would be interesting to develop games for something like this as well. But I mainly use Unity, so that won't work afaik.
Oh, I don't have any HDMI devices (except my computer monitor), so my vote goes to analog outputs! My CRT TV is waiting!
EDIT: I'd really love to see some MSU-1 support for the SNES core too. That would be soooo sweeet!
