Konami put stereoscopic 3D in a living room in 1987. The technology caught up twenty-five years later.
Nintendo's Famicom 3D System was a stereoscopic shutter-glasses peripheral released in 1987 that synchronized with the television's refresh rate to create an illusion of depth — never sold outside Japan, supporting only a handful of titles. Falsion, developed and published by Konami for the Famicom Disk System, used this peripheral to present a behind-the-craft space shooter — a perspective drawn from Sega's Space Harrier arcade game — rendered in apparent three dimensions on hardware with no native depth capability. The technology worked through alternating left-eye and right-eye frames, a principle identical to the active shutter glasses Nintendo brought to the 3DS in 2011 — twenty-four years later. Falsion's spacecraft design made a quiet reappearance in Konami's 2004 PlayStation 2 game Airforce Delta Strike as a selectable aircraft, a retroactive Easter egg for collectors who remembered. Hardware that arrives too early is not wrong — it is waiting for the world to catch up.
About this game
Falsion is a behind-the-ship perspective 3D shoot-em-up for the Famicom Disk System, released in October 1987 — predating Star Fox by six years. Flying toward the horizon in a forced-forward-scrolling perspective, the player pilots the Falsion spacecraft through enemy formations, with the option to activate genuine stereoscopic 3D by pressing Select with the Famicom 3D System shutter glasses peripheral. Only eight FDS games ever supported this glasses attachment.
The Story Behind
The Famicom 3D System — Nintendo's stereoscopic shutter glasses peripheral — was released in 1987 alongside a small library of compatible software. It was ahead of its time, but the hardware was niche and never left Japan. Falsion's behind-the-ship 3D perspective drew direct comparisons to Sega's Space Harrier arcade game (1985) and demonstrated that the FDS could power a technically ambitious experience that the cartridge hardware of the era could not easily replicate.
Tricks & Tales
The Falsion spacecraft design was later referenced in Konami's 2004 PlayStation 2 game Airforce Delta Strike as a selectable aircraft — a retroactive Easter egg for longtime Konami fans who remembered the obscure FDS game. The Famicom 3D System required batteries and synchronized the shutter glasses with the television's refresh rate — an impressive piece of engineering for home consumer hardware in 1987.
Collector's Guide
Region & Compatibility
Japan exclusive. The Famicom Disk System hardware never left Japan, making all FDS games Japan-only releases.
Maintenance Tips
The drive belt is the most critical maintenance item. The original rubber belt (approximately 31mm diameter) stretches and eventually fails after decades of storage, preventing the drive from reading disks. Replacement belts are widely available from retro hardware suppliers and require no special tools -- a documented procedure exists in multiple collector guides. After belt replacement, the drive may need alignment, which is a more involved process. The RAM adapter board contains electrolytic capacitors that should be recapped if the unit is used regularly -- leaking capacitors can damage the PCB and corrupt disk reads. Clean the battery compartment with vinegar and a cotton swab if corrosion is present. FDS disks should be stored in their cases away from magnetic sources.

What to Watch Out For
Before buying, these are the points worth knowing — from someone who handles original Japanese Falsion copies regularly.
What hardware do I need to play a Famicom Disk System game?
An FDS game requires three components: a Famicom console, the RAM Adapter (which plugs into the cartridge slot), and the Disk Drive unit (connected to the RAM Adapter). The drive requires its own power supply (six C-cell batteries or an AC adapter). Without both the RAM Adapter and disk drive, FDS disks cannot be played. The Famicom Disk System was sold exclusively in Japan and was never released elsewhere.
Are Famicom Disk System disks and drives still reliable after 35+ years?
Disk reliability varies — the magnetic media can degrade over time. More commonly, the rubber drive belt inside the FDS disk unit degrades with age, causing read errors even on undamaged disks. Belt replacement is the most common and important FDS maintenance repair. If you plan to use FDS games, have the drive belt inspected before use. A working drive with a fresh belt can read original disks reliably.
How does saving work on Famicom Disk System games?
FDS games save directly back to the floppy disk itself — there is no internal battery backup. Data is written to the disk after the save command is given, so the disk can be overwritten. To protect original game data, cover the write-enable notch with tape to make the disk read-only. Many collectors keep one play copy and one archival copy for important titles. Never power off the Famicom during a disk write operation.
Before You Buy
Things worth knowing before you buy Falsion
A short checklist for buying a used Famicom Disk System disk wisely — useful with any seller, anywhere.
-
Choose a seller who tests it before shipping
A copy that has actually been powered on and checked is a known quantity. An untested one is a gamble you only settle after it arrives.
Look for a seller who states it was function-tested and says what they confirmed. A serious seller can tell you exactly what was checked.
-
Inspect the disk and its shell
Disk System media is fragile — the magnetic disk can wear, and saves are written back onto the disk itself.
Ask whether it was tested and reads reliably; look for cracks or a warped shell in photos.
-
Make sure it fits your console
This is Japanese Famicom Disk System media and requires a Famicom with a working Disk System drive.
Play it on a matching Japanese console or a region-free system, and confirm the listing states the region.
-
Mind the drive belt on the console side
Disk System drives commonly need a replacement belt to read reliably — this is a console matter, not the disk.
If reading is unreliable, the console's belt is the usual culprit, not the game.
-
Read the seller's reviews and return policy
A 100% positive record across thousands of sales is close to a guarantee — packing, communication and problem-solving all work for everyone. A return policy protects you if something is off.
Read the feedback and confirm a clear return window before you buy.
The last step before buying anywhere is knowing what it's worth.
