If so, you are obligated to visit this site and download the pixel-perfect remake of the classic Bruce Lee game for the Commodore 64. Despite the painful graphics (the pixels are as large as pencil erasers, for pete’s sake) it’s still as fun now as it was back in the day, in 5 minute bursts anyway. PC only but the requirements are so low I suspect a non-powermac could run it in emulation.
