I did think of trying to find a convertor but none available, there was once I discovered a similar piece but got bad reviews. Multiple inputs doesnt really accept at one time. So Ultras might be a problem. Really sad for my Hori Stick, if I cant get a convertor for it its gonna end up in my local Museum. Kept perfectly with a glass box 
No biggie, theres always chances to play. As long you dun quit playing  Championship Mode This Friday WooHoo!!!
