"Super Mario Bros. Wonder" is set to be released on October 20, however, spoilers have already begun to leak on social media, revealing substantial parts of the game that Nintendo would prefer to keep under wraps. While IGN has chosen not to disclose any of these spoilers, they provide a caution for those who wish to enjoy the highly anticipated, next-gen 2D Mario game untainted. A series of now-erased tweets provided a sneak peek into game levels not yet unveiled by Nintendo, but an even bigger source of spoilers appears to be emulation.

DSOGaming reports that players are already running a complete version of Super Mario Bros. Wonder via illegal PC emulation. Understandably, Nintendo's stance on those who generate such software or leak their games is far from appreciative. In past instances, like a breach of the Pokémon Sword and Shield embargo in 2020, Nintendo severed ties with the offending publication, and recently addressed a cease and desist order to Wii and GameCube emulator Dolphin due to its debut on Steam.

Super Mario Bros. Wonder's official launch is set on the Nintendo Switch, debuting Mario's fresh voice actor as Charles Martinet, the original star, declared his retirement from the role in August. Despite these leaks, the game's hype continues to thrive, especially as Super Mario Bros. Wonder is the first full side-scrolling entry since 2012's New Super Mario Bros. U. A new power-up, introduced with the game's announcement in June, which transforms Mario and friends into elephants, has particularly captured the hearts of fans.
