If set, demo/game-specific hacks are applied to PIT timer emulation to help stabilize the demo and run more reliably.

'project_angel_demo' :
If you intend to run the Project Angel demo, use this setting. The PIT timer is forced to one of two values to resolve hangups, timing issues, music skipping on video mode changes, and VGA tearlines.

'pc_speaker_as_timer' :
A few early DOS demos apparently like to use PIT 2 as a timer source (where normally PIT 2 is used to generate a square wave to drive the PC speaker). If the demo you are running seems to run at half the normal speed for no logical reason, try this hack.

Demos that need this hack:
- Impact Studios, Legend
