1. I don't think you can play CD32 games on an A1200 without a CD32 ROM image and EUAE (although the reverse is certainly possible).
2. To uninstall a program just delete it. There is no special uninstaller except a utility on the
Aminet that deletes the files an installer script asks for.
3. There are several on the Aminet but don't expect to be able to play PC animations on a stock A1200. You'll need more memory and a faster processor than the A1200 comes with. One of my favorites is HippoPlayer in the mus/play directory on the Aminet. It plays lots of music file formats on non-PowerPC Amigas.
