You only swing forward by letting go of the ledge under your feet.
Arumana no Kiseki launched on August 11, 1987, as a Famicom Disk System exclusive, its protagonist Kaito an obvious Indiana Jones tribute — the fedora, the caves. The heart of the game is its rope: a hook fired diagonally upward, thrown early — before the jump, or on the way down from one — so that it catches the ledge your legs were never going to reach. You spend the first hour fighting it. Then one day the swing happens before you have decided to make it, and the cave you could not cross is simply a place you go now.
— inspired by Kinuyo Yamashita
About this game
Konami built Arumana no Kiseki around a rope and put it on the Famicom Disk System on August 11, 1987. In 1983 Tokuro Fujiwara had directed Roc'n Rope, a Konami arcade game built entirely on climbing, and left for Capcom that same year. Twenty years later an interviewer asked him whether Bionic Commando had been an expanded version of that earlier idea. He said yes: "Roc 'N Rope had a lot of limitations due to the hardware of the time." Kaito swings through jungle temples and across rope bridges, chasing a gem stolen from a village.
Key Features
Rope and grappling hook mechanic — launch the hook upward to catch ledges, swing across gaps, and climb to elevated platforms; Indiana Jones-style visuals with jungle temples, rope bridges, and ancient ruins; Disk System storage, which held more than most Famicom cartridges did when the format launched in 1986; Kinuyo Yamashita's soundtrack featuring her characteristically melodic Konami style.

The Story Behind
Kinuyo Yamashita scored Castlevania in 1986 under the pen name "James Banana," sharing the credit with Satoe Terashima. A year later she wrote the music for Arumana no Kiseki, with Kouji Murata arranging one of its tracks. When the Famicom Disk System launched in 1986 a disk held more than most Famicom cartridges did, but cartridges caught up within months, and by the summer of 1987 that advantage had closed. Konami kept making disk games anyway. Because the Disk System was sold only in Japan, most of them — Arumana included — were never seen anywhere else.
Tricks & Tales

Maintenance Tips
The drive belt is the most critical maintenance item. The original rubber belt stretches over the decades and eventually fails, and then the drive can no longer read disks. Fitting a new belt takes small tools: precision screwdrivers, a small hex key and tweezers. A new belt is not the last step. Afterwards, test the drive with a disk you know is good. If it does not read cleanly, the disk speed and the position of the read head have to be adjusted. The head is set against a test signal on an oscilloscope, which is specialist work. 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 Arumana no Kiseki 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 Arumana no Kiseki
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.
