OS X DOSBox/Boxer and PowerPC

I have an iMac G4 (specs in my signature) and thought it would be great to play Police Quest 3 via DOSBox on it.

It ran great at default settings but when I changed the screen resolution to take up the entire full screen performance really suffered. Before doing this there were black bars all around the screen. Is this something to be expected or could a setting be incorrect.

I tried this under Boxer and had the same results. The game runs great on my MBP but I was thinking I can use the G4 as an older gaming machine.

What about running PQ3 under ScummVM? That should get you native speed.

I agree with jruschme that ScummVM is probably the easier solution in this specific case.

If you want to stick to DOSBox however, the first thing to improve performance is increasing the emulated CPU cycles, by pressing ctrl+F11 until the game runs smooth enough. By default, DOSBox is running with 3000 cycles or something, which is equivalent to a quite slow DOS PC. If you want to change the default value, you can edit the DOSBox preferences file.
