MAS super pro blue screen

I have had a MAS super pro for the dreamcast which i purchased about a year back. I have just recently run into the issue where while im playing MvC2 I would get the controller unplugged error on my screen. When playing third strike a similar issue would occur where the game would automatically pause itself while we are playing. I have tested the stick on both first and second player so I belive the stick is having the issue. Does anyone have any suggestions regarding what the cause of it could be? Thankyou in advance.

Mas sticks for DC are known to have that problem. Just switch the pcb to a ps1 dualshock and use a converter. The next time you buy from Mas, only get playstation (or xbox 360) support and just use converters to hook it up to other systems.
