This Sega Dreamcast controller port board has been modded to replace the old, expired battery with a new battery holder, and is being sold with a new battery installed.

This mod ensures that the Dreamcast will retain its internal clock memory, so you no longer have to set the date every time you turn the system on!

It has been carefully soldered and works perfectly!

Please use the drop down menu to specify which model Dreamcast you have (model 0, model 1, or model 2). Find this info by reading the sticker on the bottom.

The circuit board will be carefully packaged and shipped right away.
