No, it's not a matter of power - unfortunately.
It's the timings. The chipsets, the UMA, it's all a mess, and some of it undocumented. Pardon the CPU architcture lingo, but the Amiga hardware was... fucked up.
Hopefully some of reverse engeneering done by Denis will be of use to WinUAE, too.
The chipsets on this thing are FPGA
. If the reverse engeneering is good it's pretty much the same thing.
