I have one of Sprow's ARM 2p, highly recommended, an
excellent development.

There's also the 'impure' GoMMC, the perhaps perfect
companion to the ARM 2p. And probably more impurity
to be found in backwaters on the net.

For speed, yes. Simplicity hardly. A 6502 core is large
and putting one in the FPGA is hardly a trivial task. To
say nothing of putting in others.

Emulation will leave enough speed for a few factors of
speed increase, compared to the real 2p. And it's more
flexible.
