Just found a Gameboy advance sp, but no games. what should I buy?

Moved into a new house. Found a Gameboy sp. Works fine, but has got no games. What should I get for it?

...

Flashcart

Metroid Fusion
Final Fantasy Tactics Advance

that is all

Wario Land 4

How do I use these?
Remember, I've never owned one of these things

I would suggest this But honestly after I turned like 16 the SP was too small for me to play for long periods of time without my hands cramping

those backlit modded GBA's look 10/10 though

Hamtaro Ham‑Ham Heartbreak

GET POKEMON EMERALD

any megaman zero

god damn the SP is a sexy fucking handheld fuck

I'd buy a new portable device but they're all garbage

Which MegaMan game is the best for a new comer

>tfw scouring eBay for an AGS-101

Mario Tennis Power Tour, it's my favorite tennis game.

i wonder what that gba sp smells like haha

Drill Dozer.

Summon Night and its sequel were decent, too.

Shining Force Resurrection of The Dark Dragon

Maybe I was just retarded as a kid, but I remember the combat being annoying as fuck because the recovery from hitting an enemy with a combo was several seconds.

I remember them being alright. Like, nothing deep, but I did multiple playthroughs specifically to get different companion dialogues.
