Walking is inconsistent in this game. It does have random advances for some reason. I tried to use walking to abuse my Entei while saved right before battling Lance and I somehow hit a frame 14 higher than my target. The best way to advance is call Elm or use the radio, bottom right is the most consistent.
EDIT: What is the starting frame for Kyogre? Please respond soon, as I only have a short amount of time before the radio changes and I'll have to wait another hour.
