Are you freezing the Traps Activated address when you change it? If it’s not frozen the value resets itself when you play through a duel.
Does the instant win work properly? I’ve had trouble getting GG to work properly on NOX 5.1, but if instant win works then the traps address should be working.
If you unfreeze all values, then play a normal duel, does the “Traps Activated” address increase as you activate each trap card?
