I'll second Megaman Starforce. And also the GBA Fire Emblem games as well. There was Blazing Sword, which u? mentioned, (It was retitled to simply "Fire Emblem" in its localization) and then there's also Sacred Stones as well, which while not as awesome, is still pretty nice IMO. Since GBA is being mentioned now, I'd also recommend Lunar Legend, which is a pretty nice one, as well as Golden Sun, both the original and Lost Age.
