NES and SNES game suggestions

[James]

I've been playing Final Fantasy 5 at great lengths lately, trying to beat it in full (meaning secret bosses and side quests and such as well). It's really starting to get to me, fighting random battles two hours straight to increase my job levels and such. Aside from SOCOM II, I don't really have any other games to use as a break from FF5. So, throw some ideas out there, please.

Edit: Oh, or MAME games, I guess.
