HELP! ACTION REPLAY GLITCHED POKEGEAR!!!

HELP! ACTION REPLAY GLITCHED POKEGEAR!!!

Okay, so I am done with the game, I defeated the Elite Four, I got the starter Pokemon from Professor Oak, etc. Etc. So, I decided to use Action Replay, I figured it wouldn't hurt. Boy was I wrong.. I played it for a while, used cheats and codes etc., and nothing seemed wrong. So I saved (major mistake on my part, I should have thoroughly checked my game to see if nothing was wrong) and I quit the game. I went back to play it a while later, and opened my Pokegear to see that I wasn't on it. After a bit of investigating I realized that it had completely gotten rid of Kanto! I can no longer see any of Kanto on my Pokegear! Nor can I fly anywhere in Kanto. Please help me with this problem, I really do not want to have to start over just so I can see Kanto again... :/ (I have tried battling the Elite Four again to see if Professor Elm would upgrade my Pokegear again, but it did not work.) (And yes, I can travel to Kanto, I just can't see where I am, and I cannot fly anywhere..) If there is anyy way to fix this, please let me know.. I am pretty desperate at this point..
