when the tvs were released in the united states, nintendo and sharp used the regular composite output only ppu, the 2c02, for the tvs. while the picture was not as crisp as with the japanese c-1, this avoided any compatibility issues. even without the rgb ppu, the picture quality for the u.s. versions of the sharp tvs were superior to many home console connections because the system was connected via a straight composite signal directly to the tv. just like the original nintendo entertainment system, it also has the 10nes region protection chip. if the game does not load, it would consistently reset, much like a normal nes system; the "p" on the channel indicator would not turn on and off, however, like the original nes's power light.
