I know this has been posted before but just thought I should point this out since it gets asked every now and then. If your games run too fast to be playable on chankast you can adjust it by press "-" and "+" to adjust the chankast internal clock. Please note that you need a desktop keyboard to use these keys on the number pad part of the keyboard(usually on the right side) Laptops' - and + do not work since they usually do not have a numpad. You can however, plugin a keyboard into your laptop and use it. For me, P4 3ghz, clocking it to 150 slows most games down to 60 fps.
