Leaf Pokemon cheat to atamaticly beat elite four?

get a GBA action replay and enter the code "battle instant win". then get all surf and strength with the cheat "all tm's/hm's and also use the cheat "all badges" and go past the guard guys and all the other victory road stuff and go to loreli/bruno/agatha/lance/rival and battle and you always attack first and you automaticly beat the trainer P.S be careful with "al tm's/hm's becuz my game froze when i opened the TM case
