This is a rather trivial port of DOSBox to MacOS X. What if you just want to play some old games? This port of DOSBox may be your answer. It's statically compiled against SDL, is built upon the Cocoa, Carbon, OpenGL, QuickTime, and AudioUnit frameworks, and thus, is only MacOS 10.3.x (or Panther) compatible. It has partial protected mode emulation, a subset of VESA 1.2 functionality (800x600x8) via S3 Trio emulation, and 'internal modem' support via the SDL_net framework.
