I'm Trapped in the Pal Park room two guys won't let me out...

Start your game over, you screwed it up, and I advise you not doing this again.

1) restart your game, because you goofed.

2) If you haven't saved, just restart the game and boom, your out.

3) If you did save, save again, turn off the game, turn put the code on the AR, then turn on the code again and walk out.

All I got...

Well, I have a simple, safe, and easy solution to your problem. All you need to do, is head on over to Codejunkies.com and find the section for Pokemon Diamond. Once you see it, you can find several different codes for Pokemon Diamond, as well as the Walk and run anywhere codes. I have no idea how you managed to delete both the Run anywhere, and walk anywhere codes, but it is of no importance to me. Anyway, all you have to do is re add the code to your Action Replay, and then you can use it to get out.

Hope this helps.

All I got to say is you can restart,add the cheat in your action replay or if you lost your action replay then buy a new one -xxxjosh919xxx

All I can say is try to find the code online again and recopy it in your action replay. Then activate it and walk out. Other then that restart. Hope this helps. P.S Thats a good cheat just be careful how you use it.

I would go to the AR section and find myself the walkthrough cheat if not restart your game.
