GrayShadow's 'Giving Gogo Magic' code

Nope, the previous save where it's 10 is from before the Vargas fight and Sabin's recruitment. If it changes to 03 properly afterward, I can check tomorrow (I sped through the game so I was not prepared to actually face Vargas, or to beat him to recruit Sabin).

When you say they're unused in vanilla, what ROM locations should I be looking at? Maybe I did put something there after all.
