Unfortunately, changing to Compatibility didn't seem to help. If you find out more, let me know.
It is noticeable, but for now, it is a small price to pay to be able to easily share these games with people that aren't really interested in setting up an emulator. We make these little GB Studio games in my junior high digital art class - and this is a nice way of showing other students, teachers, and parents what we are doing.
I'm also trying out Bubble Wrap, which is working OK as well.
Thanks again for your help.
