If you played any of the Williams Electronics or Midway arcade titles from the late 1980s through the mid-90s (NARC, Smash TV, Cruis'n USA/World, Mortal Kombat 1/2/3, Terminator 2, NBA Jam, etc) they were all done on the TMS34010 or 32031...all in assembly language.
Emulation of that processor was a bit of a challenge. Fortunately the fully general bit addressibility was only used in gzip decompression and the drawing instructions (circles, rectangles, that sort of thing) only came up in test mode. So not all of it had to be implemented and only the normal 8/16/32 bit addressing modes had to be fast.
