Phantasy Star: Fringes of Algo

Hard to tell ! So many great games
But the two Golden Sun(s) are great games !

Just a couple off the top of my head:

Mega Man II, III and V
Bionic Commando (original, not Elite Forces)
Megaman Xtreme 2
Darkwing Duck
The Little Mermaid
Urban Strike
Yoshi's Cookie
Tetris Attack
Burgertime Deluxe
Samurai Shodown
King of Fighters '96
Donkey Kong Land 2
Castlevania Legends (best Castlevania title on at least the original Game Boy in my opinion)
Operation C
Motocross Maniacs
Teenage Mutant Ninja Turtles 2:Back To The Sewers
Quarth
TwinBee Da!!
Arcade Classics:Defender & Joust (Killer music in these versions!)
Space Invaders
Looney Tunes
Looney Tunes Carrot Crazy
Final Fantasy Adventure
Game & Watch Gallery 2 & 3
Final Fight One
Megaman & Bass
Super Puzzle Fighter II Turbo
The Simpsons Road Rage

I can't think of too many GBA titles other than the last four games listed off the top of my head right now. If I do I'll add them if I can remember to.

Mother 3. 'Nuff said.

WOL BIRD : very strange for you to tell us about Mother 3 to be one of your favorite gba games ! Need to try it one day !

But also Phantasy Star Collection but beware of the glitch about the save...
