Re: [sdcc-devel] xa51 simulator

[Johan K. <joh...@id...>]

Sorry Scott, you misunderstood me: _I_ know nothing about ucsim. I just need
a simulator for the xa51 but can't spare the time to dig into it, and I'd
rather leave the expertise to the experts. My question really was: is it
possible to write a ucsim plug-in (is that the right word?) for the xa51,
and if so has it been done (probably: no) or will someone do it
