- Fan Nickname:
- Lugh is affectionately referred to as "Banana Mage".
- Many fans called Fae "chicken" because of the Divine Dragon's feathery appearance less resembling dragons.
- Marth Debuted in "Smash Bros.": Actually, in contrast to the trope namer, Roy did debut in that series, six weeks before The Binding Blade came out. For the world outside Japan, though, this remains true (and heck, he's half the reason the prequel got released internationally at all!)
- Missing Episode: Or, rather, missing downloadable content. Back in 2002, there were promotional events that gave away cartridges of the game with at least one of the four then-new trial maps. These maps were "Graizel Execution Court", "V-Type Original Map", "J-Type Original Map", and "Defeat Bandits". The problem is that none of them appeared in the original game, as they were only ever preinstalled onto the special cartridges. Unfortunately, after these events have come and gone, the cartridges that had these maps were never heard of again, rendering them lost.
- Moved to the Next Console: The game was originally developed for the Nintendo 64 and the 64DD, but got pushed back to the Game Boy Advance after the 64DD failed and development was restarted.
- Name's the Same: Morgan shares his name with the Avatar's child in Fire Emblem Awakening.
- No Export for You: Most Western players know The Binding Blade through a fan-created translation patch, as the game has never been officially localized. Its prequel averts this by being the first localized installment in the series. Thanks to Roy's popularity through Smash Bros, it's also become one of Nintendo's more visible localization gaps (and one that the director of Shadows of Valentia is on record as saying he'd enjoy closing).
- Saved from Development Hell: First announced in 1997, the game was originally going to be released as "Fire Emblem: Maiden of Darkness" for the Nintendo 64DD, being expected for release in the second half of 1998. However, despite this, there hadn't been any new information about it for a while, resulting in the game to get pushed back. After the franchise's original creator, Shouzou Kaga, left Intelligent Systems, as well as years of multiple hardware issues, the game not only got shelved, but development had to start all over again, except this time on the Game Boy Advance, finally being released on March 2002 after 5 years of being stuck in limbo, while ditching out almost everything its original 64DD self had. However, what game Maiden of Darkness had been remade to remained a mystery for a very long time until the 25th anniversary book, released in 2015, confirmed that it did became The Binding Blade.
- Troubled Production: The game started development sometime before 1997 as a title for the Nintendo 64 and the 64DD peripheral. The failure of the 64DD and shakeups within Intelligent Systems led to development being restarted and moved to the Game Boy Advance. Just about everything got scrapped outside of the characters Roy and Karel.
- What Could Have Been:
- The game was originally subtitled Maiden of Darkness and meant to be on the Nintendo 64 and the 64DD.
- The Nintendo SpaceWorld 2001 trailer revealed that originally, Lilina was meant to be playable much earlier; joining in the first chapter rather than the eighth one.
- Guinivere was intended to be playable and act as a second lord.
- Thea and Lilina may have been related.
- Zephiel and Murdock may have been brothers.
- Zephiel's weapon, Eckesachs, had durability and was intended to be acquired after defeating him. In addition, the eponymous weapon was also intended to be acquired the same way. (The latter idea would later be used in the Fire Emblem: Champion's Sword manga adaption.)
- Jahn survived his battle and would be fought alongside Idunn as a Dual Boss.
- Data exists that suggests that Blizzard might have been intended to have been a long-ranged weaponry. Evidently, Meteor was also supposed to make a return but was not coded into the game.
- There are files for a female Mercenary within the game, but it has no sprite. This may have been Echidna at some point in development before she was made a prepromote, or possibly even the basis for Lyn in the prequel.
- There may have been Dark Dragons fought alongside Idunn. Complete with droppable Dragonstones that Fae would have been able to equip. The jury's still out on if they were supposed to be mass-produced versions of the stronger version of the Earth Dragons seen in Shadow Dragon and the Blade of Light and Mystery of the Emblem, however.
- An even earlier plan (revealed in the "Making of Fire Emblem" book) had Roy becoming king of the Western Isles halfway through the game. Which would explain why the Western Isles arc feels the least integrated into the overall plot in the final game: It was originally meant to be a "find a new land" plot.
- In 2019, a full Chinese translation of the game surfaced. Apparently Nintendo submitted it to be released on the Chinese copy of the GBA, but it was never approved; if it had been, China would have gotten Fire Emblem years before they ultimately got Echoes: Shadows of Valentia.
