The '''[https://en.wikipedia.org/wiki/Nintendo_Entertainment_System Nintendo Entertainment System]''' (NES) is an 8-bit, third-generation console originally released as the '''Family Computer''' or '''Famicom''', in Japan, on July 15, 1983. The Famicom retailed for ¥14800. The console would be redesigned as the NES and released on October 18, 1985 in North America. The NES retailed for {{Inflation|USD|179.99|1985}}. It had a Ricoh 2A03 CPU at 1.79 MHz with 2 KBs of RAM.

It had a Ricoh 2A03 CPU at 1.79 MHz with 2 KBs of RAM.

The earliest games released on the Famicom suffered from significant hardware constraints due to the way the Famicom was designed: limited memory addressing (which meant games had a small maximum ROM size), how the graphics were loaded onscreen, just the native sound processing was available, no saving... To solve this problem, Nintendo came up with two solutions:

To solve this problem, Nintendo came up with two solutions:

* '''Memory Management Controllers''' (MMC), also known colloquially as '''[[#Mappers|mappers]]'''. They solved every aforementioned problem with bank switching for much more data, onboard FM audio chips, and much more. Most games released after 1986 that really pushed the system to its limits used mappers. A similar solution was used for the Game Boy.

*[[Nestopia]] also is a [[Emulation_accuracy|cycle-accurate]] NES/FDS emulator. Nestopia has issues with [[Wikipedia:The_Young_Indiana_Jones_Chronicles_(video_game)|''The Young Indiana Jones Chronicles'']] and doesn't display the status bar in [[Wikipedia:Mickey%27s_Safari_in_Letterland|''Mickey's Safari in Letterland'']] correctly (among other problems). Nestopia Undead Edition is a fork of Nestopia meant to keep it alive and fix the aforementioned bugs. This version is generally recommended over vanilla. Even the libretro core for Nestopia is the Undead Edition.

There were many accessories released for the Famicom and NES but Emulation in General only covers accessories that are truly differentiated data streams from the basic controller. For example, the Power Glove is, in actuality, just a really complicated NES controller designed to convert motion into D-PAD, SELECT, START, A, and B button commands. The same goes for R.O.B. and his  ''Stack-up'' and ''Gyromite'' games because he was really just the second player. Strangely, the Famicom has a lot more peripheral hardware to emulate than the NES.<ref>[[Wikipedia:List of Nintendo Entertainment System accessories|List of Nintendo Entertainment System accessories]]</ref><ref>[https://problemkaputt.de/everynes.htm#controllers ProblemKaputt: NES controllers]</ref>

Since most VS. System games have palettes that differ from the standard RGB NES palette, ROMs made with VS. System, which are accidentally played in the emulator's NES mode (or vice-versa), will cause the colors to be totally garbled. This can occur when there is an issue with the emulator's configuration or the ROM's iNES header.
