Notes:

This is Iniquity source code, ported to OS/2 by dink

Note from Tiny in August 2024:

"This was as he gave it
to me and from what I can remember it compiled and ran.  I just had
a quick look and while I can't test it due to no OS/2 VM right now, it
compiled in win32 VP21 with the output set for os/2."
