(and its ) are pretty good Zelda-like action adventure games. They're not going to stand up to Link's Awakening but still, I remember them fondly.

I used to like playing zoop on SNES. Fun little puzzle game,. If you enjoy Tetris, I think you'd like zoop.

Edit: my mistake I didn't realize you're talking handheld. Not sure zoop had a handheld console version.

Pinball Tycoon was one of my favorites. great music, solid no-nomsense pinball gameplay. it even had a multi-player mode! never seen another soul talk about it.

Gargoyles Quest was awesome. Love the music from Ocean games too - Hook and RoboCop come to mind.

Penguin Wars

I always thought the Triple XXX game was awesome as a kid.

Avenging Spirits. When I was younger, a friend and I loaned each other a bunch of our games. Sadly, he ended up moving away before we managed to swap back, and he got the better end of the deal when it came to the games. However, I did get left with a copy of Avenging Spirits... the game is a bit strange but its very fun and the sprite work is just adorable.

The game has you playing as a spirit who can possess enemies. You start off with a few you can possess, and then you gain more choices as you progress. Or so I believe... I wasn't all that good at the game back in the day, so I don't remember getting too far in it.
