Mario & Sonic at the Olympic Games is the first crossover title featuring characters from Nintendo’s Mario franchise and Sega’s Sonic series.

If you've come across this search phrase, you're likely looking for a downloadable version of Mario & Sonic at the Olympic Games for the Nintendo Wii, specifically in WBFS format (Wii Backup File System) — a format used to play Wii games from a USB drive or SD card via a modified (homebrew-enabled) Wii. The "upd" tag might refer to an update, patch, or a revised version of the game dump.
What is WBFS and why is it used?
WBFS is a file system developed for USB loaders (like USB Loader GX or Configurable USB Loader). Games in WBFS format are smaller than full ISO rips, as they remove dummy data and sometimes include compression. This allows you to store more games on a USB drive. Run USB Loader GX → refresh cache → play
Is downloading WBFS files legal?
Legally, downloading a copyrighted game (like Mario & Sonic at the Olympic Games) from the internet is piracy, unless you own the original disc and are creating a backup for personal use in regions where that is explicitly permitted by law. Distributing or downloading WBFS files without owning the original disc violates copyright laws in most countries.
What about the "upd" (update)?
Some game dumps include update partitions or patches. On the Wii, certain games carried system updates. An "upd" in a filename could mean the dump includes that update data — or it could refer to a fan-made patch (e.g., translation, bug fixes, or a cheat file). Always scan such files for malware if you proceed.

If you still choose to search for downloads
Be aware that many sites hosting Wii WBFS files are unreliable — they may contain corrupted data, malware, or fake links. Use a VPN, antivirus software, and check community feedback before running any unknown executables. Also, distributing or downloading copyrighted content may lead to ISP warnings or legal action depending on your country.
