Wii Save Files Updated Jun 2026

Use FAT32 with 32kb clusters. Do not use exFAT or NTFS; the Wii menu cannot read them.

Some games, like Wii Sports Resort or Mario Kart Wii , would download new content (e.g., ghost data, new Miis, or event unlocks). The save file is then marked as “updated” to indicate it contains post-launch data. wii save files updated
