Cotton 2 is an EXCELLENT game with 2D gfx smooth as butter. I've never played Cotton Boomerang and don't bother to get it since I got Cotton 2 first.
On a related note, does anybody play Cotton 2 with a 4MB RAM cartridge? Supposedly the extra RAM enhances the graphics, but by how much? Is the difference noticeable/worth getting a cart for?
(I got a 1MB cart, then found out Cotton 2 needs 2MB which only a 4MB cart can provide. Grrrr.)
