you mean you and your small group of hardcore pro-copyright friends? comon it's 2014. stuff like this and torrenting are ubiquitous.

Thanks guys, I just started playing Megaman Zero 1. It's pretty hard
I'll check out Megaman Battle Network, Fire Emblem and Golden Sun series too.

@AbsymalTorment: Right! I should totally not download a nearly-perfect GBA emulator, nor access the huge library of GBA game roms; both of which are just a few clicks away!
Go spread your excessively prudish mindset elsewhere.

Advance Wars, Final Fantasy Tactics Advance

Definitely play Golden Sun. Play the first one then the second one. The Golden Sun series is my all time favorite games, even today. It is amazing

Get the entire Megaman Battle Network series; they are bomb.

Golden Sun 1 & 2 and Megaman Battle Network 1 are probably the best games that I've ever played.

Besides the obvious ones like Pokemon (R/S/E/FR/LG), there's the Megaman Zero series and Fire Emblem.
Personally the Zero series were my favorite GBA games of all time (Zero 3 was my favorite).
