Which she is still attempting to do, and so far with
success, even with
tricksy things like VIC-II badlines (for the untutored, this is taking
advantage of the VIC-II's DMA cycle every eighth raster line and tricking
it into new and different behaviours/timing).
I still don't see the point. It's just a hardware emulation (and a mess of
wires =) when you could just as well use the real thing.
Besides, I think the coolness factor fits more into
this project than the
practicality factor, n'est pas?
Agreed, but then I'd rather she'd put that effort into something which could
be put in or onto a real C64. Adding ethernet capability to my C128D wouldn't
be that objectionable. =)

It will of course have its own native mode, and at
least on the discussion
list there are many ideas for a new OS specifically for this native mode as
well.
How about CLIPS? That seems to be 65816 native and rather advanced at this
stage. The real limiting factor in that case is the C64 resolution. IOW, a
65816 with VGA graphics /and/ resolutions would seem like a nice little thing,
though I suppose it needs some kind of selling point, which would be the C64
compatibility.
Mind you, you said "'816 core"; does that mean that there isn't a real
65816
in there, just a FPGA simulation? The fact that it is supposed to have a slot
for a SuperCPU seems to indicate that.
