Hello I have Antonio villena's mister setup the one with room for the USB drive on the bottom of the case. I also have a decapod. I was playing NES double dragon 2 with original NES controllers on the up to date mister core through the decapod with no issues.
I paused the game and went to get some water and make a phone call(10 min tops) I came back and the start button on the original controller wasn't working I then pressed the A button and it was acting like start and the B button was acting like select I then unplugged the first controller and switched to my other original controller and it was the same thing A was start and B was select.
I tried to restart the core (and reapply the snac option in the settings) and that did not work. I then tried to reassign the buttons to the NES core and mister will not recognize any inputs from both original NES controllers. I have a USB 8bitdo sn30 controller and Bluetooth controller sn30 controller and those work fine.
I then switched to the llp alternative core(can't remember the full name) and that did not work as well.
I really don't know what could have happened I don't have any other original controller like Genesis controllers to test out the other decapod ports and see if maybe the decapod went bad somehow?? (I'm assuming it's not because it never moved from when I have it but who knows)
The only other thing I'm about to do is redo mister on a small 64gb SD card and put double dragon on it and see what that does ? Maybe my SD card corrupted itself somehow??
