This is the KOF Maximum Impact Regulation "A" HDD board and USB security key set for the Type X2 arcade system.
Both the Game HDD (B Board) and USB key are original and have been tested — confirmed working and played normally, as shown in the photos (tested using a control box).
Only the Game HDD cartridge (B Board) and USB key are included; you'll need to supply your own converter, control box, and other accessories to play. This is a dedicated arcade ROM board that requires expertise and equipment to connect — please don't purchase unless you're confident you can handle the connection yourself, as support for setup or gameplay isn't available.
