Nintendo Entertainment System

The Nintendo Entertainment System, often abbreviated as NES or simply Nintendo, is an 8-bit third-generation video game console created by Nintendo. It is the western counterpart of the Family Computer, which only released in Japan. The Nintendo Entertainment System first released in North America in 1985. Unlike the Famicom, the Nintendo Entertainment System has removable controllers. Games are inserted by opening a door, sliding the game in, and pushing the panel down.

In 2016, Nintendo released the NES Classic Edition, which has 30 Nintendo Entertainment System games preinstalled. Aesthetically, the NES Classic Edition is a miniature replica of the Nintendo Entertainment System, and it does not have a cartridge slot to play Nintendo Entertainment System games.

Hardware
The NES/Famicom hardware consists of 2 kilobytes of onboard RAM, a custom second source based processor (called the Ricoh 2A03 in NTSC regions and the 2A07 in the PAL regions) which has a built in sound generator on chip and is used as the main processor. The Ricoh 2A03/2A07 contains 5 channels of sound: 1 triangle channel, 2 square wave channels, 1 noise channel and 1 DPCM channel for playing samples from memory. The Ricoh 2A03/2A07 is essentially the same as a regular 6502, but with the binary code decimal mode removed.

The video generator hardware is the Picture Processing Unit (PPU) (Ricoh 2C02 "NTSC"/Ricoh 2C07 "PAL") which is responsible for generating the sprites and background images onscreen. Graphical capabilities, extended RAM and even sound capabilities can be expanded with the use of memory mappers like the MMC2, 3, 4, 5 and Konami VRC6 among other mappers. For instance, the MMC5 adds 2 extra pulse wave channels and another Raw PCM channel in addition to the main 2A03/2A07 channels; the Konami VRC6 adds a sawtooth wave channel and 2 extra square waves and the VRC7 adds FM Synthesis capabilities which is based on the OPLL FM Synthesizer and is a derivative of the OPLL chip.

An expansion port is located underneath the Nintendo Entertainment System, although no accessories made use of it. The Famicom Disk System was planned for a North American release and if released it would have used the Expansion Port. The redesigned NES-101 Top Loader model lacks the expansion port entirely.

Trivia

 * Wario's Woods is the only Nintendo Entertainment System game to have an ESRB rating, due to being released late in the console's run.
 * Biederman Design Labs Research & Development was working on a handheld NES console called the Nintendo Express, but it never got released. On the source video's comment section, a YouTuber by the name of Rick Gordon said he worked with Paul Biederman on occasion. He also said there was a version that had a crosspad. He went on to say that Paul went directly to Nintendo, who would not approve of the system, due to the upcoming Game Boy. He lastly said that because of this, Biederman Design Labs went to Galoob who looked at it, but the toy company did not want to enter another legal fight with Nintendo.
