- Creator Backlash: Shigeru Miyamoto agrees with the sentiment that the game is just an unreasonably harder Mission-Pack Sequel of the original Super Mario Bros.
- Fan Nickname: People on YouTube have taken to referring this game as "The first ROM hack".
- No Export for You: For the longest time, the original game was not made available to western players. In addition to the original Famicom Disk System game not being ported to the NES, the Famicom Mini ("Classic NES" series in the US) port from 2004 for the Game Boy Advance was also not released outside Japan. It wouldn't be until the Nintendo Wii's Virtual Console release in 2007 that the unaltered version would finally be available in Europe and the US. It went on to see release through the Nintendo 3DS and Wii U Virtual Consoles as well.
- Remade for the Export: Part of Super Mario All-Stars.
- What Could Have Been: There were plans at one point to release the game in the west on NES as a bonus that came with Nintendo Power subscriptions, similarly to Dragon Quest I. Although an NES cartridge was supposedly produced, plans fell through due to fears of creating market confusion.
