It let you jump higher than you could, and the genre followed.
The year before, Karate Champ built the first one-on-one fighter on realism — slow, careful, grounded. Then Yie Ar Kung-Fu arrived. You could jump absurdly high. Characters threw special moves that defied physics. The game was inspired by Bruce Lee's Hong Kong films, and it chose spectacle over simulation. It became Konami's first Famicom game, and it also became the template. Every fighting game after it — Street Fighter, Mortal Kombat, all the ones you remember — took this road, not the realistic one. Turns out you didn't have to be real. You just had to be fun.
About this game
Released for the Famicom on April 22, 1985, Yie Ar Kung-Fu was Konami's very first game for Nintendo's console. A port of the MSX version, itself based on the 1984 arcade original, it brought one-on-one fighting to home players with a roster of opponents each wielding distinct martial arts styles. Inspired by Bruce Lee films, the game traded realism for spectacle — high jumps, special moves, and fast-paced action that established the template for fighting games to come.
The Story Behind
Released in arcades in Japan on October 25, 1984, and worldwide in March 1985, Yie Ar Kung-Fu was one of the earliest one-on-one fighting games. The Famicom version, released April 22, 1985, was actually a port of the MSX version rather than the arcade original, and it became Konami's very first game for the Famicom. Inspired by Bruce Lee's action films, it introduced a roster of opponents with distinct fighting styles and special moves. The game was a commercial success both in arcades and on home computers, becoming the best-selling game in the United Kingdom in 1986.
Tricks & Tales
The game's music was composed by Miki Higashino, credited under the name 『Miki-chan』, with a soundtrack released in early 1985. The Famicom version was programmed by Jimi Ishihara. The title 『Yie Ar Kung-Fu』 is a stylized spelling meant to evoke martial arts mystique, though the exact meaning of 『Yie Ar』 remains unclear.
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 Yie Ar Kung-Fu copies regularly.
Does this Famicom game have a save battery?
No. Yie Ar Kung-Fu is an action game from 1985 — you play through the stages in one sitting, and there's no save feature or password system. The cartridge doesn't contain a battery, which means one less thing to worry about wearing out.
Will a Japanese Famicom Yie Ar Kung-Fu work on my NES?
Not directly — the Famicom and NES have different cartridge shapes. You'll need a Famicom console (the Japanese original) or a Famicom-to-NES adapter. The game itself has no region lock once you solve the physical fit.
My cartridge won't start — how should I clean it?
The gold pins on the cartridge edge are almost always the reason. Wipe them gently and lengthwise with a cotton swab dampened in 90%-or-higher isopropyl alcohol, then let it dry fully before playing. Never blow into a cartridge — the moisture in your breath corrodes the very pins you're trying to clean.
Before You Buy
Things worth knowing before you buy Yie Ar Kung-Fu
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.
