with 12 more Ruby & Sapphire Challenges left, i've come up with a way to to check for altered Pokemon cartridges. it's very simple: mix records and if they dont recieved the eon ticket, then their cartridge has been altered. ok, let me explain how it works. if you read the back of the eon ticket instructions, there will be a section that says "SHARE THE EON TICKET!" look under "CAUTIONS" and number 5 says "if you or your friend has an altered Pokemon cartridge. you may not be able to transfer the EON TICKET ..." so in order for this to work, the TO or HJ would need to have a gameboy that had an eon ticket in it. Players would then make space in their backpacks and mix records with the TO/HJ's gameboy. if the eon ticket transfers, then that players cartridge was not altered. Keep in mind that this will only work if the players do not already have an eon ticket in their game, and the TO/HJ's gameboy can't share eon tickets an infinite amount of times.
