Does your computer have 233 kB free contiguous memory? And is there a C compiler for it?
Then you can port Doom to it. Well, enough parts of Doom to run timedemo 3, in black and white.
32-bit CPU, 16-bit CPU. Little-endian, big-endian. It's all possible. No FPU required.
Implement i_system.h. Look at i_ibm.c and i_mac.c for examples.

Footnotes
-
Two compilers can build the IBM PC 16-bit port. Gcc-ia16 produces faster code than Watcom. The static code analysers of both compilers detect different issues. ↩
