The FC Twin Video Game System is a Famiclone that can play NES and SNES games. The system has been well received due to the increasing scarcity of original hardware.

[edit] Compatibility

The FC Twin Video Game System has separate circuitry and card slots for both hardware NES and Super Nintendo Entertainment System, allowing it to play games for both consoles. It features a single-pole, double-throw power switch with open position; the switch can be thrown to 8-Bit (NES) or 16-Bit (SNES), or opened to Off.

[edit] NES compatibility

The FC Twin console uses SNES compatible controllers and devices such as the Super Scope, but cannot use NES compatible controllers and devices such as the NES Zapper peripheral for Duck Hunt. The Super Nintendo controller buttons otherwise map to the NES controller inputs (B maps to Y, A maps to B. A, X, L, and R serve no function).

The FC Twin connects through an RCA connector, and can be hooked into a surround sound system. When using stereo and surround output from these systems, NES sounds and music may seem very different from their typical mono output. Using output modes that properly generate mono sound, either through a single center speaker or cloned to multiple speakers, the sound output sounds mostly identical to the original NES. The FC Twin does not produce some sounds faithfully, even with mono output; sound effects in the Super Mario Bros. series games will for example immediately seem different.

The FC Twin uses a card slot reader rather than a ZIF connector. The second-generation NES also used a card slot reader, and featured no 10NES lock-out chip. Both the official NES2 and the FC Twin capitalize on the card slot reader's greater reliability; games rarely suffer from bad connections as they did with the original ZIF socket. In the FC Twin, the NES cartridge still has to be reseated occasionally; the pins can misalign and short across each other, or otherwise fail to connect properly.

As tested by consumers, the following NES games are not compatible with the FC Twin:

[edit] SNES compatibility

The FC Twin uses Super Nintendo compatible controllers and devices, and can thus connect to specialized input devices such as the SNES Mouse for Mario Paint.

The FC Twin reproduces SNES sound flawlessly.^{[citation needed]} The SPC700 in the original SNES used a sample-driven mechanism similar to a type of instruction-driven MOD file. Reproducing the sound from these systems simply requires playing back clips of sounds with mathematically-defined effects and loop points.^{[citation needed]} As long as the CPU can read the instruction language or run a program to emulate it, this task presents no difficulty.^{[citation needed]}

While the FC Twin is Super Famicom compatible, two plastic tabs in the cartridge slot prevent them from fitting. These tabs must be removed- or otherwise worked around- to play Super Famicom titles. Similar tabs are used in the American Super NES. Note that it is not PAL compatible in any way as so a universal adapter is necessary to play PAL games.

As tested by consumers, the following SNES games and peripherals are not compatible with the FC Twin:
