- Cowboy BeBop at His Computer: The US television commercials, Nintendo Power's first walkthrough article and the magazine adds for the game referred to the sword that struck Bowser's castle as "Smithy the Sword." This is not the sword's name, Smithy being a completely different character. In addition, the Nintendo Power walkthrough article and the magazine ads hinted at a subplot involving Geno becoming a "real boy".
- Exiled from Continuity: The reason why Geno, Mallow, Smithy and many others aren't even namedropped in most other Mario games is because Square Enix owns the rights to the characters who debuted in this game, not Nintendo. It took 7 years for Geno to make another appearance (showing up as a cameo in the Star 'Stache Smash minigame in Mario & Luigi: Superstar Saga), and 11 years from that for him to get referenced as a Mii Gunner costume in Super Smash Bros. for Nintendo 3DS and Wii U. Super Smash Bros. Ultimate does a bit of legwork on this, having Mallow as a spirit and Geno as a spirit and profile icon.
- No Export for You: This game joined the ranks of Final Fantasy VI and Chrono Trigger during the SNES era in Europe. At least this one had more of an excuse due to Nintendo needing to rework the included lockout chip to be compatible with PAL televisions. Twelve years later, the European Virtual Console set things right thanks to the Hanabi Festival.
