GOG did a good job here, really captures the old school gaming without many hassles. CD switching (virtual) is instant and automatic and the game requires pretty little tinkering to work, runs nice and stable. IMHO they should set initial cycles at 20k with up down being the same, or even 10k; 35k is so incredibly high that it’s hard to aim unless you get close or are facing a planet (game will slow down there, that isn’t changeable so no fault of GOG on that) and no computer of that era would run the game so fast. Not hard to fix with a bit of reading about DOSBOX though. Otherwise terrific job.
