I just realized that the only place this is mentioned is in the
Startup-Sequence on the game disk, and that anybody who is
likely to have a SAGE-compatible video card is also likely
to have a hard disk.
Megafortress uses a SAGE-compatible video card if you have
one installed. The only card I had to test this with is the
DMI Resolver, but it works fine on that. The support is
limited - only the Pilot screen and External Camera screen
are shown on the resolver, but it does look nice in 800x600
If you have Mega and have a Resolver, then read the LastMinute.Txt
file on disk 1 for info on how to get into it.
