A Fire Emblem game was in development for the Nintendo 64DD add-on; A CD drive add on for the cartridge based system. Nintendo, however decided that the 64DD would not sell and gave it a limited release in Japan before both the 64DD and it's games were canceled, or moved to the Nintendo 64 for a cartridge release.
The Fire Emblem 64 game however possibly then went on to become Path of Radiance later in life, finding a new home on the Gamecube.
Below are a few screenshots of a very early build of Path of Radiance, which seems to have a N64 quality to them.
