Twin Famicom Complete Guide



1. What is the Twin Famicom?

  • Released in 1986 by Sharp in collaboration with Nintendo.

  • Combines both the Famicom cartridge slot and the Famicom Disk System in one unit.

  • Designed to solve the hassle of connecting separate hardware (original Famicom + Disk System).

2. Key Features

  • Two-in-one design: Play both cartridges and disk software.

  • Unique look: Bold red/black or green/black colorways.

  • Improved reliability: Built-in FDS drive (though still prone to belt wear).

  • AV output: Some models include composite AV for clearer picture vs. RF-only Famicom.

3. Model Variations

  1. AN-500 Series (1986)

    • First model.

    • Color: Red/black or black.

    • Uses controller cords fixed to the console.

  2. AN-505 Series (1987)

    • Improved design.

    • Detachable controllers, slightly revised case.

👉 Collectors often debate which version is “best.” In practice, both are good—condition matters more than version.

4. Common Issues to Check Before Buying

  • Disk Drive Belt: Often stretched or melted. Needs replacement.

  • Pin Connectors: Cartridge slot may loosen over time.

  • AV Output: Check if the console has AV out or only RF.

  • Controllers: Cords and buttons may require cleaning or repair.

  • Power Supply: Original adapter vs. modern replacement.

(At Enjoy Game Japan, we clean, test, and often replace belts with fresh Japanese rubber belts to ensure smooth gameplay.)

5. Why Collectors Love It

  • A symbol of late-80s Japanese game culture.

  • Convenient way to enjoy both cartridge classics (Super Mario Bros., Dragon Quest) and disk-only gems (Zelda, Metroid, Akumajō Dracula).

  • Distinct Sharp design makes it a standout piece on display.

6. Buying Advice

  • Budget:

  • Junk (for repair/parts): $50–80

  • Working but unrefurbished: $100–180

  • Professionally restored/cleaned: $200–300+

  • Where to Buy:

    • eBay, Yahoo Auctions, retro game shops in Japan.

    • Always check seller notes on belt replacement and cleaning.

7. Care & Maintenance

  • Store in a cool, dry place (avoid disk drive mold).

  • Use silica gel packets for moisture control.

  • Run the disk drive monthly to keep it moving.

  • Avoid cheap belts—use proper Japanese rubber replacements.

8. Final Thoughts

The Twin Famicom is not just a console—it’s a piece of history.
If you’re starting your retro collection, it offers the broadest game library of its era in one machine.
