Identify these games?

[Mobster]

Hi guys

I’m hoping you guys can identify what games these are.
Names on the title screen are there but When I try and look them up I cannot find any mention of them.

1.Pokémon card stadium
2. Pocket monsters pickachu stadium

I believe they are for the game boy color

Just want to know if these are real games or rom hacks?
