This little black game pak has four old Konami games on it, although I have only heard of two of them. It has Pop 'n' Twinbee, The Mystical Ninja Starring Goemon, Bikers and Guttang Gottong.The games are quite simple to play and being from the Game Boy Color the graphics and music a very simple too.
Konami are clever though, the have included shoot 'em Up, RPG/action, Sport/Racing and Puzzle games into one pak so you get quite a variety.
The games are fairly easy though and once you have played them one through you probably won't play them again.
Pop 'n' Twinbee just isn't the same without a multiplayer cooperative mode, which could have been included.
I'd only recommend this to someone who played and loved at least one of the titles it carries, otherwise your precious money could be much better spent
