In Red and Blue Rescue Team, to evolve you must first beat the game. When you go to Whiscash Pond, there will be a massive hole in the center of the area. This is Luminous Cave. Make sure that you have your stone on hand and that the pokemon you want to evolve is alone. Upon entry, a mysterious voice will ask if you want to evolve. Say yes, and when it asks if an item is necessary, say yes as well. The stone will be used and your pokemon will evolve.
In Explorers of Time and Darkness, and Explorers of Sky, you must graduate from Wigglytuff's Guild to gain access to Luminous Spring. However, you won't be able to evolve. Once you have defeated Palkia, and Manaphy has returned, can you evolve.
