Mario Club build games

The Mario Club builds of Nintendo games seem to have been used by the Mario Club division of Nintendo for debugging purposes, as evident by unused text that specifically refers to a "Mario Club version" (or similar). It is assumed due to internal non-disclosure agreements, specifics regarding these builds are not meant to be public knowledge.

Regardless, efforts in data-mining some official releases support their existence.

Games with evidence of Mario Club builds

• The Legend of Zelda: Ocarina of Time Master Quest (leaked prototype version)
• Pikmin 2
• Wii Sports

Notes

In video game development, it is not uncommon that debug menus and features are left in the final version, and there are many Nintendo games with debug menus, such as the original Custom Robo having an extensive one.

There have also been leaked debugging versions of Pokémon Gold and Silver Versions (demos), Pokémon Ruby (in German) and Pokémon Diamond and Pearl Versions.
