I got an original copy of Star Control II and I am playing it under DOSBox in my Windows 7. It all works beautifully.
However, the game come with a file named "keys.exe" which does affect the keys in Super Melee, but it does not affect the keys in the game itself: it seems to be "stuck" on Enter and Space only. (ordinary shot and special shot)
Anybody have an idea? Maybe it's something with the DOSBox and the way it maps the keys? Although it's not likely, as in the Super Melee which also runs under DOSBox it works fine.
