I bought WC1+2 last night and haven't been able to play them because they run at such a high speed that it makes them almost unplayable. I've seen this problem posted by other users but none that have said how to fix it on a mac.

I'm not sure if this info is useful or not but both Privateer and Strike Commander run at normal speeds.

Edit: In a rush. Forgot to post this as a question and I have no idea how to change it

I had this issue with WC 2. There's supposed to be commands that let you slow down or speed up CPU cycles so the game runs faster or slower, but I've never gotten those commands to work on GOG's boxer setup, so you'll have to go to the application file for each game and go to 'Show Package Contents', and navigate into the .boxer file within, find the DOSBox config file, and change the cycles setting. You'll have to experiment with different numbers to find the one that's right for your computer. You can use this guide to see what appropriate values you can change the settings to:
