Well don't you feel smart for using an AR. Perhaps you should have thought of the potential consequences before using a random cheat you pull off the internet made by someone you have never met before. If you have tried everything you can to get rid of them, you can try cheating. If your game is already bunged you can't bung it more by cheating. Or the more plausible option of restarting your game and play without the usage of AR hoping that you have learned your lesson.

Oh my, that is terrible, I see what the problem is though. When the person who made the code actually created the Pokemon in the said code, he did not change the amount of Pokemon used. Since he or she did not change it, it will take up all Six spaces in your Pokemon Party. Still, even with the code doing that you should still be to remove or deposit any Pokemon from your party that you want to. If you cannot deposit the Pokemon into the Pokemon Center computer then perhaps you could at least get two of those Pokemon and place them in the daycare in Solaceon Town. You could try taking the Action Replay out of your Nintendo DS, and then playing the game to see if you can get rid of them. If you cannot dispose of them, then the most likely case as to what will happen is that you will have to start over, and never use that cheat code again. Hope this helps.

That's really bad man you can try trading and or you can leave them at the daycare.

Your game is messed up
