Just for information.
All games which I checked from Andromeda Software uses this kind of emulation or whatever. I checked Moon Patrol, Crystal Castles, Millipede, Robotron 2084.
Some time ago (two years ago or something) I started with Crystal Castles and I really stuck with this. When I find some free time then I back to Crystal Castles. Or perhaps I should start with easiest and smallest Andromeda Software game.
This is only speculation but I think that script system is kind of 8-bit emulation. Probably Andromeda Software have access to original 8 bit sources and semi-automatically do such conversion.
