Shank, a hardware modder and hardcore Nintendo fan, has managed to cram a fully-functional Wii into a tiny Altoids tin. Dubbed KillMii, the final product is apparently actual Wii hardware as the result of a project that began in April 2017. Despite being portable, the device is said to have a measly 10-minute battery life. You can check out some footage of Super Smash Bros. Melee running on the tin in the embedded video below:
Kill Mii: Portable Wii in an Altoids Tin
I made the worst Wii Portable ever. This is a REAL Wii, not an emulator, in an altoids tin. This project took about a year and was miserable to complete.
