I beat Wario World 3 eventually, it great at the time. Played on switch it doesn't hold up.
Would sometimes beat Super Mario Land on long road trips to holiday destinations, occasionally won Tetris.
Zelda Oracle of seasons was pretty good, but i couldn't figure out how to progress & we didn't have the internet. Searched every location, interacted with all the stuff..

Final memory of the device was leveling on Pokemon Crystal in bed at night, with a special Gameboy light.
Had Jurassic Park but it was dino-poop
