So your compiler doesn't support anything besides 16-bit DOS? (Dunno, never used VC 1.52 or any version at all, really.) Try Open Watcom (no cost, open source): it supports any DOS, OS/2, Windows, and partially GNU/Linux. It also comes with a bunch of DOS extenders and has helpfiles included. I'd guess that Causeway probably supports VESA, but I dunno for sure.

Of course, if you ever intend to run on Windows Vista (or similar), DOS full-screen apps won't work at all. In that case, you have to port it to Windows (or run under something like their Virtual PC 2007).
