I'm experiencing a weird problem with the Super NT where I can't enter the menu by pressing "select + down" on my 8bitdo SF30 Pro. The down and select buttons work individually when I'm in a game, but not as a shortcut to enter the menu.
I checked the settings and "select + down" clearly is the configured shortcut to open the menu. Strangely, "select + up" to reset the game still works with the 8bitdo SF30 Pro.
I'm currently running fw version 4.1, but had the problem with 3.9 as well.
It works without problems with an original snes controller and with the 8bitdo SFC30. Any ideas?
