I was updating my list in the Online Rarity guide and do have two Gameboy cartridges which I couldn't found there:

"Card Game" it's a Japanese game, the English title is only on the box, on the cartridge it's written in Japanese.
(DMG-CGA, Coconuts, 1990)

"Pro Action Replay"
(Datel)

In case somebody needs pics, I can make them and send them in a mail.
