Upgrade EPROM for Dead or Alive 2 NAOMI. If you open your Dead or Alive 2 NAOMI cartridge, installing this EPROM will upgrade it to the Millennium Edition. There is only one ROM to replace, and NO SOLDERING is required :)

This upgrade to Millennium edition unlocks additional game modes, and I'm also told it unlocks additional costumes for the characters.

This listing is for the upgrade EPROM only. The Sega NAOMI cartridge itself is not included. You are responsible for knowing how to properly remove the old rom as well as properly orient and install this one. If you have any doubts please ask before installing. The chip and PCB socket in your game are marked for the proper direction of installation. You literally only need a Phillips head screwdriver and the ability to remove a socketed EPROM (very small flathead will work if it has to).

Chips are verified 100% on an EPROM programmer before shipping.
