The Nintendo 64, often referred to as N64, is a 64 bit video game console released in 1996 by Nintendo. It is the most powerful cartridge based non-handheld system ever produced. The console does not provide an RGB signal and must be modified in order to provide one. Not all N64's can be modified for RGB, most notably no PAL consoles can be RGB modded.
