Up for sale is an authentic, original North American copy of Dr. Mario for the Nintendo Entertainment System (NES).

The cartridge has been completely opened, deeply cleaned, and fully serviced for premium performance and long-term reliability.

Maintenance Work Performed:Deep Board Clean:

The circuit board has been entirely cleaned of vintage dust and debris. (Note: The native hardware layout used for this game inherently does not utilize internal save batteries, making it incredibly stable and long-lasting).

Pin Restoration Treatment: The gold edge contact pins have been thoroughly polished on both sides, cleared of all surface residue, and treated with a preventative layer of DeoxIT chemical solution to ensure instant console booting and optimal data transmission.

Condition Note:The internal board is pristine. The game functions flawlessly and has been comprehensively bench-tested on original hardware: it boots up instantly on the first try and plays without any freezing or crashing.

The exterior grey plastic shell is in solid physical shape. The front label is fully intact with excellent gloss and vibrant colors, showing only minor age-related cosmetic shelf wear from previous storage (please see photos for exact condition).

Perfect, clean copy for a collector or gamer who wants an absolute puzzle classic to add to their retro lineup!
