There's a large number of ships in
Command Adventures: Starship. The graphics files are something weird, can't tell what they are opening them in a text editor, perhaps a binary editor might tell something? Could be they're something perfectly common with the header info stripped off. There's 52 files in the SHP directory.

Sizes from 23K to 330K.
Screenshots of all the ships can be got from the Ship Edit screen at a starbase.
The game will run with DOSbox and the D.O.G. frontend, I can send you the profile I have it working with.
Sound files are RAW PCM data, music files are just MIDI files with different filename extentions.
