I use Norton Commander 5.0 in a graphic mode as a shell (it doesn\'t slow down the work very much) and some games:
CGA 320x200 games: Space Commander, Cat, Paratrooper, Arkanow (type of Arkanoid).
EGA 160x100x16 games: King\'s Quest II&III.
EGA 320x200x16 games: King\'s Quest I&IV, Hero\'s Quest I&II, Deathtrack, King Graham\'s Backgammon, Commander Keen 4-6, Keen Dreams.
EGA 640x200&640x350 games: Zeliard.
VGA 320x200 games: Magicland Dizzy, King\'s bounty, Blake Stone (I suspect it\'s a protected mode game), Wolfenstein 3D (ran on my PS/1 286 but also protected mode game if I\'m correct), Duke Nukem 2D, Raptor (protected mode game), Quest for Glory III&IV (protected mode games).
That\'s just to name a few. If you have in mind certain game that you know how to run smoothly - please tell me and others, maybe we\'ll find out if this recipe works for other games.
BTW, please notice that even the most simple CGA games with PC Speaker sound run REALLY slowly. It seems to be the matter more of improper configuration/compilation, than of the real lack of MIPS on Z (mine is 760 one).
