GrayShadow's 'Giving Gogo Magic' code

Well whatever methods you're using, if it changes properly from 00 to 03 after Vargas with a one or two playthrough (one doing all possible stuff) you should consider this solved. Monitoring $1E3C is a thing you could do, to check where it change the value to 10, if it happens again. Not sure if snes9x does real time changes you might have to press break to see the RAM viewer change. I don't have any other solution for now.
