Someone apparently managed to port GTA: Vice City to the Nintendo Wii.

Yes! Exactly what you're reading. Apparently, a Reddit user managed to port GTA: Vice City, and it is fully playable with great performance on Nintendo Wii.

According to Reddit user Optijuegos, some tools were created from scratch while others served as a foundation to make GTA: Vice City playable on the Nintendo Wii. Along with some technical details, the developer also shows a capture—recorded on VHS as a personal stylistic choice—of the port running on what really appears to be a Nintendo Wii. Of course, the download link for the port—known as reVC (or GTA: Vice City Wii)—is available below.
