In Pokemon Emerald, there is a slope you can go up that will keep pushing you down. You can use this to your advantage by taping the button down while having Pokemon in the daycare to get levels, but, for some reason, it isn't working for me. I have tried this before and it was fine, but now it won't level the Pokemon. I have tested walking in other areas and I get levels, but the slope trick won't train my Pokemon. Why is this?
