the emulator you have in your collection. There's a thread about it on the
Lemon64 forum with a contribution from the original author. POKEs work, but
there's no Z80 emulator so 
machine code games won't run. I doubt a £12.95 emulator would include a Z80, so
I wonder if the Video Vault solution was just a rebranded version of the Whitby
Computers program, only with more marketing BS. The C128 could emulate a
Spectrum quite easily 
as it has all the required hardware, but it would be about a third the speed of
the original. So yeah, kind of pointless.

Probably, though at one time I used the old software IBM PC emulator on
my Amiga to run PASCAL when I was studying as I didn't have a PC at that
time and it got me out of trouble.

It was slow, but worked well enough to get the job done.
