Well, it certainly won't require 7.x on install if you just copy the files over And if it does, someone screwed up the installer. Continuum uses DirectX 3 if I remember correctly. Not sure about the audio... Hmm... I'll try to check... yeah, it uses DirectSound but you can turn sound off However, I discovered that it actually uses DirectDraw even if you enable software emulation... what kind of software emulation is that... wtf...
