Hudson's RPG side-scroller on Famicom. A Xanadu spin-off — towns, dungeons, equipment, and a dying world tree.
Faxanadu was developed by Hudson Soft as a side-story to Dragon Slayer II: Xanadu, published by Nintendo for Famicom in November 1987 — a side-scrolling action RPG featuring an elf returning to the World Tree to discover it dying, overrun by dwarves and monsters. Players purchased weapons, armor, and spells from shopkeepers in towns carved into the tree's trunk and branches. The world was constructed as a series of interconnected vertical environments. Faxanadu sold approximately 800,000 copies and was well-received in North America where it was published by Nintendo.
About this game
Released in November 1987, Faxanadu is a side-scrolling action RPG set in the World Tree — a giant tree whose branching trunk forms the game's vertical world. A wandering hero returns to find his homeland of Eolis invaded by dwarves from below the tree, and must climb through its ever-stranger branches and roots to find the source of the corruption. Licensed from Nihon Falcom's Xanadu engine, the game blended Falcom's RPG structure with Hudson's action design instincts into one of the most atmospheric and unusual Famicom games of its era.
Key Features
A continuous side-scrolling world built around the World Tree's vertical trunk, an RPG experience and gold system with equipment upgrades available from shopkeepers in towns, magic spells that cost MP and provide combat and traversal options, password-based save system via a monk in towns, and a tone of melancholic isolation unusual for Famicom action games of the era.
The Story Behind
Faxanadu took its name from a portmanteau of Falcom and Xanadu — the game was built on a licence from the PC game Xanadu (itself a sequel to Dragon Slayer), which Nihon Falcom had produced for Japanese computers in 1985. Hudson's adaptation moved the concept from keyboard-controlled PC RPG to Famicom action RPG, a significant translation that required redesigning the input, pacing, and visual language. The game's Western name is the same as the Japanese; in North America it was published by Nintendo of America, unusual for a Hudson-developed title.
Tricks & Tales
The password system in Faxanadu uses a monk character in each town — the player tells the monk they need a 'Mantra' (the in-game term for password), and the monk provides a string of characters to record. This was one of the more narratively integrated password systems of the era, making the mechanical necessity feel like a story-world interaction. The game's melancholic ending, in which the hero saves the tree but returns to an existence of wandering, was unusual for a Famicom action game. Nihon Falcom has its own developer listing in the museum's creator database, connecting the PC Xanadu lineage to this Famicom adaptation.
Collector's Guide
Region & Compatibility
Famicom and NES are the same hardware family but use physically incompatible cartridge formats — Famicom carts have a 60-pin connector and a narrower shell, while NES carts use a 72-pin connector with a wider housing. You cannot insert a Famicom cartridge into a North American NES slot without an adapter, and vice versa. The Famicom itself has no lockout chip, so any Famicom cartridge from Japan will run on a Famicom console regardless of origin. If you are buying a Japanese Famicom cart to play on a NES, you will need a 60-to-72-pin physical adapter; if you own a Famicom, Japanese-market software is your native format and no workarounds are needed.
Maintenance Tips
The gold-plated edge connectors on Famicom and NES cartridges pick up skin oils and oxidation over decades — a gentle wipe with a cotton swab dampened in 90% or higher isopropyl alcohol, stroking along the length of the pins rather than across them, is the accepted standard. Let the alcohol fully evaporate before reinserting. The old habit of blowing into a cartridge is folklore: the moisture in breath causes slow corrosion of the contacts over time, and any improvement you felt came from the act of re-seating the cart, not from the breath itself. Nintendo eventually updated its own troubleshooting guidance to say explicitly: do not blow into your Game Paks.

What to Watch Out For
Before buying, these are the points worth knowing — from someone who handles original Japanese Faxanadu copies regularly.
Will this Japanese Famicom cartridge work on a North American Nintendo Entertainment System (NES)?
No, not without an adapter. The Famicom uses a 60-pin edge connector while the NES uses a 72-pin connector with a physically different form factor — the two are incompatible at the cartridge slot level. Third-party adapters exist that bridge the pin difference and allow Famicom cartridges to run in a NES. On a Japanese Famicom, NES cartridges face the same incompatibility in reverse. To play Japanese Famicom software, you need a Japanese Famicom, a Famicom-compatible clone console, or a NES fitted with an appropriate adapter.
How should I clean a Famicom cartridge to ensure reliable play?
Apply 90% or higher isopropyl alcohol to a cotton swab and gently wipe the gold-plated PCB edge contacts on the base of the cartridge. Never blow into the cartridge — breath moisture accelerates contact corrosion over time. If cleaning is needed inside, Famicom cartridges use 3.8mm security game bit screws (not standard Phillips); a security bit screwdriver is required to open the shell without damage. Note that most Famicom boot failures originate in the 60-pin console slot rather than the cartridge itself — cleaning the console slot contacts separately with a contact cleaning tool is often the more effective fix.
Before You Buy
Things worth knowing before you buy Faxanadu
A short checklist for buying a used Famicom cartridge 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.
-
Make sure it fits your console
This is a Japanese Famicom cartridge with a 60-pin connector; a North American NES uses a 72-pin slot, so it will not fit directly.
Play it on a matching Japanese console or a region-free system, and confirm the listing states the region.
-
If this title saves your progress, check the battery
Cartridges that save use a small coin-cell battery that fades over decades — a dead one wipes your save without warning.
Ask the seller whether the save function was tested. Replacing the battery is possible, but doing so erases any existing save.
-
Check that the contacts are clean
Dirty edge contacts are the most common cause of startup and sound trouble in cartridges of this age.
Choose a seller who cleans the contacts before shipping. A note that it was tested and cleaned means the basics were handled.
-
Confirm it is genuine, not a reproduction
Sought-after titles are targets for reproduction boards with replacement labels.
Ask for a photo of the circuit board and look for factory markings. Favour a shop with a licensed second-hand dealer permit (古物商) — by law its stock has a traceable origin, your simplest guard against fakes.
-
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.
