I hear ya, NovaCoder. I dont want an i7 + GF9800 attached to a 1200 keyboard either. (With winuae i kind of have that already)
Rather, Id like to see something that the AAA chipset (or maybe the "Hombre") would have brought to the Amiga world.
Im pretty sure that playing Quake2 @640×480 would be possible.
That's why I'd like to se SuperAGA in an FPGa.. not because it would be anywhere near modern GPUs but it would feel like an Amiga we would have gotten maybe in 1995 if things had turned out a bit differently.
