Earlier this month, Nintendo stealthily issued a Wii firmware update in Japan — version 4.1 — designed to fix an unidentified issue in Wii Sports Resort. The supplied changelog is rather vague, mentioning only that this update includes “behind-the-scenes fixes” designed to improve system performance.

If the same Wii Sports bug exists in overseas copies of the title, rest assured it is fixed with firmware 4.1. On another note, Nintendo warns that 4.1 will check for modified save files and automatically remove them. Avid users of homebrew beware and update with caution.
