Pokémon was all I ever really played, tho. I had Wario, Kirby (the one where you had to move the whole Gameboy to play), Power Rangers, and Donkey Kong games, tho.
Yes I had this one too untl one day... my gameboy was on my kitchen's table and it was there an inteir night. Then my dog somehow climbed the table and pissed on the gameboy
Your dog probably got jealous that you paid more attention to your gameboy.
I remember synching with other kids to battle in Pokemon. They'd always get mad that I'd win all the time because all of my Pokemon were at level 100. I used that multiplying cheat with Missingo on Cinnabar Island.
