26. Q: What does Altering Cave do? All I find is Zubat!
A: The speculation was that we would be able to change the Pokemon in Altering Cave through Wonderspots. These are machines that you use Mystery Gift with, and they've been used at Pokemon Rocks America and the Pokemon Center in NYC to give out the Tickets for Deoxys and Lugia/Ho-oh. Unfortunately, there have been no Wonderspots for Altering Cave (in Japan or elsewhere), so it's basically a feature that they probably had every intention of doing something cool with, but just never did for whatever reason. The Altering Cave Pokemon can be obtained in Emerald, Colosseum, and now in Pokemon: XD.
Um there were no e-reader cards for altering cave, not even in japan. The japanese have no way to change the pokemon there.Alternating Cave is for E-Readers which we dont have! It good to EV train in speed thou.
The games coding has been processed and all the pokemon possible to find in there were found out to be johto pokemon. No event was ever made to trigger the change as the quote from the FAQ a few posts above shows.Well the page on FR AND LG said you might be able to get legindarys if you had the right card.
I belive that might be psoible but very unlikly.
