- Fan Edit: ROM-hacker and YouTube user Iván Delgado, who also colorized Super Mario Land 2: 6 Golden Coins has spent over a year working on a rather impressive colorization project for the game. Dubbed For the Frog the Bell Tolls DX and inspired by the official full-color re-releases of several notable titles for the original Game Boy, the project modifies the game based on how Delgado believes it would look if it were a Game Boy Color game. Colorization hacks are common, but typically fall victim to Sturgeon's Law, so the current high-quality results of the project have earned it acclaim from people both inside and outside the source game's fanbase. As of this writing, the colorization project is still under development.
- Fan Nickname: The Prince of Sablé is referred to simply as "Sablé" by the long-time fans.
- Fan Translation: One was released in 2011 and is currently the only way to play the game in English.
- Marth Debuted in "Smash Bros.": This happened with three characters, at different points in time in different games. Prince Richard made his Western debut in The Legend of Zelda: Link's Awakening (accompanied by this game's Recurring Riff and lots and lots of frogs) within a year of this game's release, and Dr. Arewo Stein made his Western debut in Wario Land 4 (which features him as yet another object thrown by Wario to activate switches) nearly a decade after this game's release. Not long after the game itself turned 20 years old, the main character, the Prince of Sablé himself, appeared in Super Smash Bros. for Nintendo 3DS and Wii U as an Assist Trophy, putting him in a situation similar to that of the Trope Namer, sans an official localization for his debut game.
- Prop Recycling: Some sprites and sound effects and the font are reused in The Legend of Zelda: Link's Awakening. Both games even run on the same engine.
- What Could Have Been: An official DX remake was announced for the Game Boy Color, but was soon cancelled.
