1.0 System ROM Required Hewlitt Packard graphing calculator. No real problems emulating this. The window is a bit large on an 800x600 screen, but is certianly useable. Port of ID software's popular game Doom. Sound support is there, but graphics are limited to 320x240 8bpp, it won't run in 16bpp mode.
Sound support is a little skippy.
It needs the real WAD file from Doom, Doom II, TNT, or The Plutonia Experiment to run. Mac Doom WAD files work fine with it. Makefile and source trees are reworked to be easier to manage.
