Can you load a gba pokemon game for diamond and pearl pal park?

I do not think it is work but one day I think it will.

Nope, it is not supported. But it's a small feature that will probably be easy to do, and maybe it will be in the next release of No$GBA. :)

Thanks. I'm no where near completing the pokemon league so it will most likely be there when I do get to access pal park. Hopefully.
