At first I laughed for a while. Then I investigated. I found:
http://jcpti89.free.fr/prog/halflife.zip
and became convinced that IT MIGHT BE POSSIBLE!!!
But it would be a much more difficult port than the
Linux or Macintosh port. IMHO. You would certainly
have to find an assembler and an emulator that runs
on Windows. If you find a sucker ....no, no, I mean
if you find a volunteer..... to try such a thing I think it
would be neat and I would provide a lot of help.
Then the total process would be something like:
1)Disassemble 68000 machine language.
2)Translate to C++
3)Translate to TI assembler.
