Hi guys

As has been said the Book Openings (CBO) and Great Games (CGG) cartridges are compatible with the Silver Bullet. The Advanced Chess cartridge (CAC) also works with the Silver Bullet giving it 6 levels instead of 8.
As far as I know it functions the same as a CAC in a Mini Sensory or Mini Sensory II.

I also have the cartridge price list. There are 14 cartridges plus the cartridge adaptor for the Prestige. Do you have the compatibility page for all the cartridges? I do not have that, and know of no internet source for that information.

All the best
