UPNetwork -> Pokémon Video Games -> Pokémon Ruby/Sapphire -> Mystery Event

The Mystery Event option in POKéMON Ruby & Sapphire is used to unlock trainers, berries, and events via the Nintendo E-Reader.

What is Needed:

• Two Gameboy Advance, SP, or Player systems
• One Gameboy Advance Link Cable
• A copy of POKéMON Ruby or Sapphire
• One Nintendo E-Reader
• A Battle-e, Enigma berry, or Eon Ticket card

How to Activate:

• You must have beaten at least the first 5 gyms.
• Go to the POKéMON Center in Petalburg City and talk to the person standing next to the compute.
• When he asks for a profile, enter "MYSTERY EVENT IS EXCITING."
• After that, save, and restart your GBA by turning the power off and then on.
• Now the option for Mystery Event will be seen in the main menu under New Game.

Using the e-Cards:

• Place the E-Reader in one GBA and turn it on, then do the same for your R/S game pak on the second GBA
• Connect the purple end of the Link Cable into the GBA with your game pak and the other end into the E-Reader
• On the E-Reader go to Communication -> To GBA
• On your game go into the Mystery Event option
• Hit the A button on each system and wait until they are connected
• Once that's done, slide an e-Card through the reader and it will send the date to your game

What's Left:

If you loaded an Enigma berry or Eon ticket card, go to the Petalburg Gym. Normal will be in the first room. Talk to him and he will give you the new item.

If you loaded a Battle-e card, go to the old mans house in Mossdeep City. Speak to him and he'll let you down into the basement where you will fight a new trainer.
