- Try a different music library, one where you can "pole" the sound
- routines every retrace or so. I think GoldPlay allows this, (assuming
- you're playing a mod).
-
- Also, you can try and limit the number of colours that you cycle
- ie don't cycle the whole palette unless you really have to.
-
- good Luck.
