This music though...

I dunno, I always called it 8-bit music. XD

It definitely is 8-bit, but it sounds more like it came from one of the older Pokémon games rather than a Fire Emblem game. XD

pretty sure its either from the VERY first one or an 8-bit remix of the series theme

It sounds like a 8-bit rendition of the Fire Emblem Theme. Maybe from the NES version of Shadow Dragon, aka the OG Fire Emblem

It IS the original FE theme, on 8-bit.

Duplicate reply, D'oh.

It's the title screen theme from the first Fire Emblem game on the NES.
