Man, I must be incredibly dense, because every one of these games runs terrible on my PC. I've tried messing around with the DOSBox speed controls (Ctrl+F11 and Ctrl+F12) but gameplay seems really laggy and jumpy. I had really fond memories of PT 109, but every time I fire on an enemy, or get shot at, the game freezes up for 10 seconds and plays a blaring MIDI tone like it's trying to talk to the mothership from
Close Encounters.
What the heck am I doing wrong?
