While Sonic Mania was never officially released for the Nintendo Wii, a dedicated community has made it playable on the console through a homebrew port based on the Retro Engine (RSDKv5) decompilation. This allows the game to run natively on the Wii (and vWii on Wii U) at a smooth 60 FPS with support for 240p output, making it a favorite for CRT enthusiasts. Essential Requirements
