i am a speedrunner interested in utilizing the effects of the mail glitch in japanese sapphire as described here.
a particular application i am interested in is its ability to skip surf. i found that if you use the glitch to walk on water, then corrupt a tile into the secret base entrance (using a phrase such as "golduck", like in this video), then enter and exit the door, you will enter a surfing state regardless of whether you have a pokemon with surf, or even the balance badge, or even hm03. this could be accomplished on route 118 to skip most of western hoenn, in theory.
the problem is that the tile corruption always affects the same 9 tiles on a given map, making such an exploit impossible on maps where the location of the corrupted tiles does not permit walk-on-water. the wiki link above provides a table of coordinates of the corrupted tiles, but these coordinates appear to only apply to the mossdeep city map–other maps have their own coordinates. i am curious how the game decides which tiles to corrupt when using the mail glitch, perhaps a bit more of what the mail glitch is/does, and perhaps how we could exercise more control over which tiles become corrupted.
thanks,
