For the X68000, this is a conversion adapter for SEGA Mega Drive controllers to use 3 buttons with certain doujin software, including Street Fighter and Fatal Fury. It does not function as an MSX standard. (Shipping is conversion) #PC-9801 #PC-9821 Created by cutting a new extension cable, rewiring, and attaching terminals. The Mega Drive pad's bottom row of terminals, B*GA, is converted to BA*G. The * switches the reading, allowing all three buttons to be used only in specific software. The terminals use high-tack adhesive, so the top and bottom cases can be removed. In that case, replacing the bottom row with ABG will result in the MSX pin configuration. Remove the *.
