Ever since Forza Motorsport 4 introduced the ability to create your own artwork and livery designs for cars in the game fans have been attempting to replicate their favourite real-life designs; and while this is usually limited to racing car designs, such as that used on the Subaru Impreza, some have opted to recreate alternate design choices.
Specifically the Famicom and Super Famicom; as Twitter user @t__ken has recreated their appearance for use on selective cars within Forza Motorsport 6. The Famicom design has been tailored to the 1987 Pontiac Firebird Trans Am GTA where as the Super Famicom deisgn is tailored to a Corvette. Of course the same designs can be used on other cars found within the game; but they would require additional tweaking by the user.
A selection of screenshots showing the Famicom and Super Famicom designs in Forza Motorsport 6 can be found below; and the designs themselves can be downloaded via the Forza Motorsport livery and decal design service of the game.
