For those where don't know what is Sega Naomi:
Sega Naomi is an Arcade system based from Dreamcast, but Sega added more ram to make it powerfull and people to don't stop to go at arcades. Some games also had on the front of the Naomi control panel an port for your lovely Dreamcast controller and can load from VMU just like regular Dreamcast.
I Interested to the Sega Naomi and I plan later to build my Sega Naomi collection. If I would manage to hack the Sega Naomi, I Will turn it to multi system to play DC games on it.
