I started playing Emerald few weeks back. I wanted to use cheats here. I had put the master code and the master ball code which works absolutely fine. But whenever I use pokemon code nothing happens. Keep in mind, I play On my Android phone in the GBA emulator (not the John lite version). Once I put the Pokémon cheat and then use the PC in Pokémon Center the game just freezes.
I don't know what the problem is but when I searched about it many people claim that they had it worked on their cell phones.
The code I'm using is for Bulbasaur: 83007CF6 0001, which I obtained off the supercheats.com site

What probably happened to you is a "Bad Egg" has appeared in your pc, causing your game to freeze. Basically, bad eggs have a chance to appear when you cheat and getting rid of them isn't that easy. If you want to research more about bad eggs, you can read about them more in this link. Bad Egg
