You need to cap the framerate to 60 (for the first 3 games) and modify a value in regedit for modern widescreen (see pc gaming wiki but the value depends on your system). MyAbandonware has downloads for the original disc versions and magipack repacks with dgvoodoo framerate fixes pre-installed, but cutscenes don't always work in those versions.
