First of all hello to the lxdream forum. Thanks a lot for developing this emulator also for OS X users.

I am a fan of MK4 and was searching for the game and emulators for a little while. Then I found here.

Game Speed: %70(min)-%80 average, it's going at a stable pace.

Glitches: Church zone sometimes has a brown texture glitch under the screen. Doesn't affect gameplay though.
Sound: No sound when fighting or at the menu. Videos have sound though.

I didn't have crashes during the game.

System: Mac Pro 3.0 ghz (2006)
OS: Snow Leopard 10.6.2
GPU: ATI Radeon 3870
