Ever heard of the program
Boxer? No? But maybe of DOSBox, an MS-DOS emulator for the Mac? Boxer is a special version which is specially made for games. It allows you to play the classic MS-DOS games which are often more fun than today's blown-up games.
Hmmm... MS-DOS as game platform? There were games for it? Yes, there were! I was surprised, too. On the demon there is a 8 gig-sized package with more than 2300 games and three packages with preinstalled games for the Mac using Boxer. There are a lot of conversions, for the Amiga, the C64 and Arcade games.
Here's a classic game to test:
Turrican II. The gfx looks a bit different compared to the Amiga version, but the sound is the original and the game is real fun. I created a .dmg which includes Boxer 0.72 and a readme file which also includes the cheat.
The installation is easy: Create a folder called 'Boxer' in your Applications folder, put Boxer into it and start it once. A MS-DOS window will appear, you can close it. Now copy the Turrican II file to the folder and start it like a normal application.
Have fun!
