Spice86

Spice86 is an experimental emulator, whose support for Stunts is being worked on as of 2025. At present (2025-03-01) it can start the game, but no sound is played (start with -a ns to avoid wasting cycles on that) Additionally, one must give the parameter --InstructionsPerSecond 5000000.

The reason for this workaround is that Stunts activates interrupts in the middle of the int 8 handler (see here), so another int 8 can could be triggered in between. This interrupt corresponds to the programmable interrupt timer, which Stunts sets at 100 Hz. So if the int 8 handler needs more than 1/100 seconds to run, disaster ensues. This probably never happens on real CPUs, but might occur if the emulator's simulated CPU is too slow with respect to the simulated PIT.
