This is an early prototype Nintendo Power GB Memory Cartridge. The label on the front of the cartridge indicates that this was used at some sort of seminar during 1998.

It predates the final release by two years and is notable for containing an early menu with different music, and even a completely cut track. The cartridge also contains the following games, although please take note that these are of course the same as the final revisions: Tetris, Yakuman, Tennis, Dr. Mario, GB Wars, and Yoshi’s Cookie.
