The team that built Pokémon built this first.
Pulseman was released in July 1994. Satoshi Tajiri directed it, Ken Sugimori designed the characters, Junichi Masuda composed 34 tracks for the Mega Drive, and Atsuko Nishida drew the graphics. One year later, the same core team at Game Freak released Pokémon Red and Green. Pulseman had an electricity-surfing mechanic and a techno-influenced soundtrack that Masuda described as inspired by German electronic music. It sold modestly, and the game is barely remembered outside Japan. The team that would build one of the highest-grossing media franchises in history was, at the time, building something small for a console most people had stopped buying. Nobody was watching.

About this game
Pulseman, published by Sega for the Mega Drive in July 1994, was developed by Game Freak — the studio best known for Pokémon, which they would release the following year. The player controls Pulseman, a human-computer hybrid who can ride electrical currents at high speed and transform into a ball of pure electricity. With 34 original tracks, composer Junichi Masuda created a soundtrack inspired by German techno using the Mega Drive's FM synthesis — one of the most technically accomplished and distinctive soundtracks on the hardware.

The Story Behind
In North America, Pulseman was distributed exclusively through the Sega Channel digital subscription service in 1995 — it never received a physical cartridge release outside Japan. This makes original Japanese cartridges among the more collectible Mega Drive items in Western markets today. Game Freak had previously developed games for various platforms before partnering with Nintendo on Pokémon; Pulseman represents their period of independent development.
Tricks & Tales
The electricity-surfing mechanic — where Pulseman transforms into a ball of electricity to ride power lines and zip through the environment — required the Mega Drive's FM synthesis to produce sound effects and music simultaneously at a high rate, which Masuda called one of the most technically challenging aspects of the game's production. The game's Japanese name 'Pulseman' and the character design themes of electricity and transformation were later echoed in several Pokémon designs.

Region & Compatibility
Physical cartridge release in Japan only. North American distribution was via Sega Channel subscription service only (no physical NA cartridge).
Maintenance Tips
The cartridge edge connector — both on the console and the cartridge itself — is the most common source of read errors on a Mega Drive. Clean the cartridge contacts with a cotton swab lightly dampened with 90% or higher isopropyl alcohol, and let them dry completely before inserting. Avoid blowing into the slot; moisture accelerates pin corrosion. For persistent problems, the console's cartridge slot pins can be gently cleaned the same way using a thin swab.

What to Watch Out For
Before buying, these are the points worth knowing — from someone who handles original Japanese Pulseman copies regularly.
Will a Japanese Mega Drive cartridge work on a North American Sega Genesis or European Mega Drive?
Not directly. Japanese Mega Drive and North American Genesis cartridges have different physical notch positions, preventing direct insertion without a pin adapter. The console also enforces regional settings in hardware — a Japanese cartridge on a Western console will often lock up or refuse to boot without modification. Playing Japanese Mega Drive software is most reliably done on a Japanese Mega Drive. Region adapters and mod chips exist for those wishing to run imports on Western hardware.
How should I clean a Mega Drive cartridge?
Apply 90% or higher isopropyl alcohol to a cotton swab and wipe the gold-plated edge contacts on the base of the cartridge. Most Mega Drive cartridges use standard Phillips screws if the shell needs opening for deeper cleaning. Clean the console's slot separately — oxidized slot contacts are a common cause of boot failure on Mega Drive hardware.
Before You Buy
Things worth knowing before you buy Pulseman
A short checklist for buying a used Mega Drive 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 Mega Drive cartridge; it differs in shape and region from the North American Genesis and may need a matching console or adapter.
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.
-
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.
