Ive seen some Game & Watch games that don have the Game & Watch logo. Why is that?
A. It could be bootleg copies. Most of them came from Russia. Also some companies put their own Logo there (with Nintendo’s authorisation of course) to use as promotion items such as Bosch on Turtle Bridge, Candia on Popeye and Mickey Mouse and Alsthom Atlantique on Popeye. These games are quite rare and were only available in about 200 copies.
