My Pokemon Diamond keeps crashing when I go to Pal Park. Can anyone please tell me what wrong?

Question

When I find a pokemon ive sent from a GBA game it crashes

Answer 1

did you ever hack your game?

i dont think that should crash it.

i heavily hacked my emerald and its doing as good as it did when i got it

sorry but if they found out you used an AR they wont swap your broken game for working...

Answer 2

do you use an AR (action reaplay) or maybe is the ds second hand that could be it.

Answer 3

It shouldn't do it. Your game might be defected. Sorry man.
