I'm gonna guess it has something to do with the AP >.< (I had the exact same AR as you! That was well before i got into the scene XD)

 

AP stands for anti piracy. Flashcarts weren't effected in this way but i can't think why else it would mess up. Try to put (M) and a basic code like x99 of masterballs on. It could be an unstable code causing the loop.

 

Oh well... Thanks for helping me out.

Resetting my Action Replay and formatting it completely twice did the trick. :/

Hope this doesn't happen again in the future.

Unstable code? I was pretty sure the code works!?

Yet again, thanks for helping out.

 

A mod once told me I'm allowed to bump if people don't answer after a day...

Can anyone help me out??

 

I resetted my AR completely and put in only the DEFAULT codes. It worked the first time I used HG with AR.

Thanks for trying to help anyways

if you think no one could help you in the forum
or
you are not getting any good answers to your problem
i think you should contact datel and ask why
afterall, its their product and they should have a proper solution for you

 

i am not sure about the US side but i know the EU/JAPAN side is pretty active

 

UPDATE: I made a huge discovery everyone!
I noticed that if I try to load Action Replay and Pokemon Heart Gold in my other DS lite, not the pink one shown, it works fine!
So the problem must be with the combination of AR, Pokemon HG and the Pink DS lite altogether.
I thought maybe I should reset my DS lite back to factory settings and start over, and so that didn't work either. The problem still persists on the same DS.
Anyone got a clue?

 

What's that?

 

The metal pieces on the AR and DS sides that come in contact with each other (so they can transfer data).
