Most games should have a frame rate limit set. The option is off by default, which is the source of the problem you're seeing, but there's an easy solution to the problem with most games that should be standardized.
If you have SGDK, you can open the project, go to the Player Settings (The Key icon) and check the "Limit Frame Rate" checkbox, then save it and quit. Then it should play properly.
If you don't have SGDK, just open the .gdp file in your text editor of choice, find the FPSLimit=0 and change it to FPSLimit=60
