Actually (if my memory serves me right), FE 1 & 2 were for NES, and 3, 4, and 5 were for SNES. And as you know 6, 7, and 8 are for GBA (7 being the first released in America). Then there's FE 9 for Gamecube.
And you're asking for just regular pics, right? Just wanting to make sure before I go posting a bunch of stuff.
Yup, that's all of those. We NEED many more though. The FE girls=horribly underrated and underused!
And rather than post all the pics myself, you can go on Google and type in Fire Emblem art and go to the second link. It has pictures of almost every FE character that has art of them.
And here's a direct link to another site that has a bunch that the other doesn't (as the lack of Igrene from the first appalled me).
Actually, if you don't mind them smaller, Eaichu's archives has every character from FE6, FE7 and FE9. FE5 FE8 are there, but there's only a handful. TCG scans are from FE1-5, if I'm not mistaken.
