Trainer/Gym Leader rematches through code Pokemon Emerald.

[Ixkli21]

This was made by some guy named Oykawoo, it's a code for Pokemon Emerald:

Maxie and Tabitha fight (L+Sel) [Oykawoo]
155A9BC1 356CB00C
A751EBF9 7364DED0

So, technically, this is another rebattle code... that fight with Steven Stone? My question is: can other one-time fights like that be accessed through codes like this? e.g., the battle with Tabitha at Mt. Chimney? Or maybe, rematch Archie through codes like this?
