I've gotten a glitch, or something close to that.
On the way to Mikan Island, I hit this forest, not sure of the name though.
I lost because all I had was a Pokemon with Splash (I think it was a Feebas or Magikarp), so I got transported back to the Valencia Island Pokemon Center.
When I tried to retry my battle, and tried to get passed the stairs on the way there, it says something like "Humm..." and then a whole bunch of Spanish words, which were translated into something like "We shouldn't go back here because we should talk to Professor Oak to get back to Pallet Town.".
Probably a scripting problem, where the script says "right when you enter the forest, you can never turn back.", which shouldn't be hard to fix (by the information I know about scripting.)
Anyways, this hack is probably one of the funnest games I have ever played, and the leftover Spanish words make the game very original and lets you learn some Spanish.
(And, obviously, the words "Si" or "Non" are common".)
