i got a mini controller recently and when i try to play i cant hold triangle and square or even press them without the other stop working i have it set up
Like they don't respond like the connected triangle and square notes I can't do that one will shut down and one will stay on but when I'm not holding them at the same time they work
Sure it was a ghosting problem, in this case i can't help you since it was a hardware problem. The only way to fix this is buy a new keyboard that support anti-ghosting keys.
