Hello everyone its chosen one the number one friend anyone could have...

1) To get Snorunt you go to an ice cave go deep in and you should find one.

2) To get in the back room you (don't know if its true) find his wifes boat at sea to get the key.

3)I'm not sure if you can

4) No idea how much Action Replay cost check ebay

5) To Trade from Ruby/Sapphire you must beat the pokemon league in Fire Red have sixty Pokemon get the National Pokedex and go to One Island talk to Celio bills friend he will ask you to find a ruby it is on Mt. Ember the cave is guarded by Team Rocket the Sapphire is on Six Island but a scientist will grab it before you, head to 4 island go to the Rocket Warehouse beat the maze (kinda like the one at the Game Corner basement) beat the scientist get the sapphire go to Island one give him the Sapphire and ruby and you can now trade to Ruby/Sapphire.

You're asking on the wrong game, so I'll assume that you're getting the answers from Ruby.

1. Snorunt is in the Shoal Cave. Every six hours the tide will fluctuate, granting access to certain areas and chambers. During low tide you will be able to work your way through the cave to a chamber coated entirely with ice. Snorunt should appear there periodically.

2. Connect your Game Boy Advance with a Ruby or Sapphire cartridge to anothyer with an E-Reader in it. Then, activate Mystery Events on Ruby or Sapphire, and then take the Battle Card that you got with the Ruby or Sapphire cartridge and swipe it throught the E-Reader. A dialog box should appear on the game, stating 'A new trainer has arrived in Hoenn.' Go straight to that house and talk to the inhabitant, who will be standing in front of the door. Say yes and he will allow Lady Astrid or Gentleman Nils to come out for battle. Defeat him or her and register 69 trainers in Trainer's Eyes in the PokéNav and you've got yourself a star on your Trainer Card.

3. No.

4. It depends on the retailer and availability.

5. In the Sevii Islands on Fire Red you will have to battle what's left of Team Rocket and salvage the Ruby and Sapphire Plates. Turn them in to Bill and that should trigger a feature that will enable you to Trade with Pokémon Ruby and Sapphire.
