Since Data East's fall, tracking the source down seems hard, especially as many game companies of that era failed to preserve the source for many of their games.

Might be interesting to see how GOG got their Dark Sun bundle [0] running. It's backed by DOSBox, but the midi driver seems different, and some of Ravager's frequent bugs have disappeared.

Maybe a partial remake like you suggest in your article?
