About this game
10-Yard Fight is an American football game by Irem, first released in arcades in 1983 and ported to the Famicom in 1985. As a NES launch title in North America, it was one of only two not developed by Nintendo.
The Story Behind
10-Yard Fight was developed by Irem and released in arcades in December 1983, where it topped Japan's arcade earnings charts in early 1984. When Nintendo launched the NES in North America in 1985, 10-Yard Fight and Kung Fu were the only two launch titles not developed by Nintendo — both were Irem arcade conversions. The Famicom port (Japan, August 1985) was published by Irem; the NES version (North America, 1985) was published by Nintendo. The NES port added two-player simultaneous play and defensive gameplay, which the arcade original lacked. The arcade version ran on Irem's M-52 hardware and was distributed by Taito in Japan. The game used a vertical-scrolling field with a top-down perspective, a design approach that would influence later sports games. In Europe, the game was released as Vs. 10-Yard Fight in arcades.
Tricks & Tales
The arcade version was offense-only — players advanced toward a touchdown with no defensive play. The NES port by Tose added both defense and two-player simultaneous mode. 10-Yard Fight topped Japanese arcade earnings in early 1984, making it a proven hit before its home console release. The NES version was published by Nintendo internationally, while Irem self-published the Famicom version in Japan. The NES version included five difficulty levels representing different leagues: high school, college, professional, playoff, and Super Bowl. Players had to win each level to advance to the next, with the final Super Bowl stage considered extremely difficult. The game's simple control scheme used only two buttons — one for passing/kicking and one for running/tackling.
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 10-Yard Fight copies regularly.
Does 10-Yard Fight save progress or high scores?
No. 10-Yard Fight is a single-session arcade-style game with no save feature, no password system, and no battery backup. Scores are lost when the console is powered off. This is normal for early Famicom/NES sports games — they were designed to be played in one sitting, like the arcade original.
Are the Famicom and NES versions the same game?
Yes, the gameplay is identical. The Famicom version (Japan, August 1985, published by Irem) and the NES version (North America, 1985, published by Nintendo) are the same port developed by Tose. The only difference is the cartridge shape and region — Famicom cartridges have a different physical format and won't fit directly into a standard NES without an adapter.
Before You Buy
Things worth knowing before you buy 10-Yard Fight
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.
