Second Reality - Running The Demo

Running The Demo

While the demo code remains freely available on numerous Internet sites, it is difficult or impossible to run Second Reality directly on a modern PC. The demo used its own memory manager which accessed the MMU directly in a way which is not compatible with modern operating systems, accessed video and sound hardware directly (using its own built-in device drivers), and many of the timings in the demo do not scale up to modern CPU speeds.

To run this demo on a modern machine running Windows or Linux, one can use DOSBox. DOSBox is even capable of emulating the exotic video modes and the Gravis Ultrasound preferred by Second Reality.

The demo runs best on an Intel 80486 PC with a Gravis Ultrasound or a Sound Blaster Pro (or register-compatible clone).
