I've turned my Street Fighter Arcade1Up cabinet into a mame machine, I got a PC inside with Big Box etc, I was looking for some light guns to add the finish touch but they are out of my budget currently, so I've decided to use a Gun shell and a Wii Mote for the time being, but it seems like when I set my Dolphin Bar in mode 2 my entire big box just freezes, like none of the controls work on the control panel, my keyboard and mouse don't work, the only thing that works is the Wii mote that acts as a mouse cursor, Anyone have a way to make this work all together? If this isn't allowed here please remove! for example, I open up Area 51, I hit tab on my keyboard to bind my buttons, and I hit the trigger on the blaster but nothing pops up, it seems like it can't recognize some of the buttons on my wii mote - Thank you
