A grand idea, Maneki, though I'd choose a few of the more obscure Capcom titles.

Strider: No argument here. It's a great action/platformer.

Black Tiger: Agreed.

Eco Fighters: A little-known horizontal shooter, it might be a tight fit for the GBA, but it'd be great to play this one outside of the arcade.

Ghosts N' Goblins: There's already a Ghouls N' Ghosts remake on the GBA, so it would be only fitting to port the original.

Varth: Capcom's tribute to the Raiden saga, it's solid stuff.

Wonder 3: Yeah, I'm cheating here, since this is three titles in one. They're all great games, though, and I think the GBA could handle the port.

Unfortunately, I don't think that the GBA could handle Alien vs. Predator, Battle Circuit, Armored Warriors, or any of the company's other graphically intense beat-'em-ups. I'll just have to save up for that Supergun.
