I meant the other way around, my bad. The DMG style GameBoy carts could probably be played in the clone console this cart came with. From the appearance of another comment, it likely would have been a keyboard with cart slots big enough to accommodate genuine DMG style cartridges on it.
Cartridge for a Bootleg GameBoy. This particular game was also available for a Famiclone system. It probably can be played in a DMG GameBoy.

Not compatible with the DMG, this cart is fatter, and less wide. See photo in another comment I made.
