The Altering Cave, in the Japanese versions, allowed the players to capture Pokemon like Smeargle, Houndour, and other Johto Pokemon after and e-Card was scanned using the e-reader. During the translation into English or whatever language you would call this, Japan released Emerald and Coliseum, which also had the Pokemon that the Altering Cave had. So...NoA decided to kill off the e-Card thing for the Altering Cave. Which is what we have now: a huge empty cave with murderous Zubats.
