You can run Tomb Raider 1 (maybe TR2). However, the more recent games will not run. No OpenGL games can run in Sheepshaver due to the fact there is no support to speak of which allows OpenGL games to run.
Remember that Tomb Raider will run only under software rendering in Sheepshaver, since Quickdraw 3D support is limited at best and Glide isn't compatible at all.
then you should programming a classic runtime, like the wine runtime for windows applications. crossover is much faster then a complex windows emulator. i guess a classic runtime like crossover (windows runtime) would be much much faster.
You can install very small game such as wolf,tom rider,boxing etc Because Pear Pc is not good for game. It will do slow your pc. So my advise is, don't install any game.
