With the release of "Bomberman '93", it was revealed that TurboGrafx-16 games can support full five player games. Since a single Wii can only have four Wii Remotes and four GameCube controllers connected at the same time, a combination of the two are needed for five player games. The same issue is found in 5-8 player Commodore 64 games as well. Because the Wii U doesn't have GameCube controller ports, only up to four player games can be played on the system.
