you need an e-card reader and e-cards, which you can buy in Japan etc. if u scan the cards in, then whatever Pokemon is on the card will appear in the game in the alterng cave
Altering cave is on 5 or 6 island.
There is no Altering Cave in Pokémon Platinum.
A special Mystery Gift could be used to make it possible to encounter shuckle in the Altering Cave, but that Mystery Gift was never distributed.
You can't do anything with altering cave unless you have an E Reader.
There are no moveable rocks in Altering Cave.
It's normally no pokémons in the altering cave i heard that you must do something ;)
Altering cave does not change into traveler's cave. Altering cave can only offer new Pokemon (since all it offers are zubat) after using Mystery Gift.
No.
It is a mysterious cave filled with Zubat. If you did something with the Mystery Gift and a Wonder Spot, there would be 8 different Pokemon found there, but Nintendo hasn't yet done anything with it. In summary, it's useless (unless you need a Zubat).
Only zubat can be found in Altering Cave. Altering Cave was a location intended to be used for an event where Mystery Gifts could change the pokemon encountered in the cave, but these Mystery Gifts were never officially distributed.
Alter, Alters, Altering are all different forms of "Alter" in the present tense.
You can't get to the Altering Cave in Pokémon Pearl because there is no such thing in Pearl.
