Mike,
First off, kick ass cabinet and kollection!
I am curious about your button layout on this. I actually prefer the same standard old school MK layout that you have used here with the block in the middle and the run under the thumb. This causes a shortage of buttons though as well as a couple of other issues. I recently built a fight stick for MKX and used the exact same layout, but I am having some issue mapping all of the buttons because of the lack of one. Basically you have to pick either level interaction or throw for your thumb, one or the other. Is there another way you have found to get around this? I know there are a few shortcuts, like block+3+4 to initiate an xray.
