   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.
