Baseline (Widescreen) Solution & Issues
The game window can be maximised to most resolutions (set windowed mode in Acabal.ini). The game's resolution will be increased to render at the maximised resolution, but the aspect ratio is not maintained (everything is stretched from 4:3).
The game window can be made mostly borderless with Borderless Gaming (menu bar will still be visible).
Some higher resolutions may require dgVoodoo 2. Some very high resolutions will crash the game ("Error: ===> ACabal95: IDDraw::CreateSurface returned DDERR_OUTOFVIDEOMEMORY) ===>").
