...especially if it was a text-mode game (I guess the trouble with FPC
output comes from buggy console support which is probably not that well
debugged in DosBox because that's usually not very important for games). I
may be completely wrong though. ;-)

...or you can compile with -st and (assemble and) link under DosEmu /
DosBox if the DJGPP binutils work correctly with either of them... Not
necessarily very elegant, but a possible solution if you cannot find or
compile the cross-binutils.
