About Elm messages
To verify your seed, you must have go to kanto by following the story (collecting badges, beating the e4, getting on the S.S Aqua, and finding the girl). Even If you use the walkthough wall code and go on the ship to kanto or just go to kanto, the elm method will not start to work.
About the pokerus, I transfer a pokemon with uncured pokerus and I receive the message from Elm.
About Irwin method
If you use the walkthough wall code and beat Irwin, you will still be able to check your seed and advance it, like elm
And after you defeat Team Rocket in Goldenrod City, you will be able to verify your seed by Irwin again.
If you alternate between elm and Irwin, your frame will advance normally as if you were just verify your seed using one of them.
When I decided to RNG Ho-oh, I like the date roll over. My frame had advance by 2. I don't know if it the advancement will be consistent or not.
Disclaimer: Using walkthough code & No trainer battle to get quicker access to pokemon, get to Irwin, and rng legits jirachis before 7/16/2010
