that proves a button matrix is programmable unless it is all Shift registers???, I just can't figure it out in MMJoy2-2016-11-01 (see above thx.)

Only 2xCol and 1xRow I used for switch with LED indication (for GEAR) and another one switch. All others are connected to Shift registers. But I do not know what is problem with button matrix? I used it in my previous project w/o problem. I usually use matrix button 6x6 so it is enough for 32 buttons and HAT. I do not understand why do you set rows B3 then 8xNothing and B1???? Same problem in COL between D6 and E6. I allways set it in a row w/o gaps. Then do not forget to set buttons numbers at the table on the right side and "Save sets to device". Must work. This picture may help you:
I recommend you use last stable version of MMJoy2 so version [20160818upd1] that is w/o BUGs but button matrix must work at any version.
Due to your picture you can use 11 free pins so max you can make matrix of 5x6=30 buttons. You made only 2x9=18 buttons and I think problem is bad setings of SW MMJoy2. If you want post here picture or scheme of your connections and then I make you settings and post here picture of MMJoy2 software settings. OK?
