Blah blah blah MS system (of play), new Metal Slug game, yadda yadda Trevor & Nadia are the new characters, something about time attack etc. etc.
That ¥38000 price down below is for the 1-slot MV1C motherboard by the way, not an expensive home cartridge.
*If you recall, Sun Amusement was named the company that would be handling Japanese MVS & NGH releases in Japan after SNK's demise.
