On , Nintendo officially closed the Wii Shop Channel. This meant that new users could not create accounts, and existing users could no longer add Wii Points to purchase new games. While users could still re-download previously purchased content for a time, the ability to legally purchase Mega Man 10 on the Wii hardware vanished.

This "DLC" approach on a retro-styled game was a point of contention among fans, though the base game alone offered a complete narrative experience. The primary reason the search term "Mega Man 10 Wii ROM" has gained traction is due to the closure of the Wii Shop Channel.

However, the release was not without controversy. Capcom utilized a segmented release strategy. The base game cost 1,000 Wii Points ($10), but additional content—such as the playable Bass character, an extra stage (Special Stage 3), and the Endless Attack mode—had to be purchased separately for a few hundred Wii Points each.
