Nothing much to say, start with IKARI.COM, press Enter when asked
to insert EGA disk, it's being emulated as B:.

To run the game in CGA mode (for whatever reason), start with
IKARICGA.COM instead.

Keys:
Arrows+Home+PgUp+End+PgDn - Move
Z - fire gun
X - throw grenade
Ctrl-Q - Quit (added by Demonlord)

The game messes with the system timers, and I'm not sure if I set
them back correctly, so the system time might be affected by this...
