Why “v5661”? Because that was Nintendo’s last official IOS56 version. I kept the number to fool signature checks. But inside? 64’s bones, 56’s muscles, and a stitch of my own.
: The Wii uses multiple "IOS" files (Input/Output System) stored in slots on its internal memory. Each IOS acts as a mini-operating system that a specific game or app requires to interact with the Wii's hardware. ios56-64-v5661.wad
