Like Forgotten said, gssp is supported, but you'll have to use the (m) code in order to work since they are encrypted... and when you use a gssp, the other code types doesn't work anymore, so use just gssp... if you try use a unencrypted code with the gssp active ones, vba may also crash
would be good if PokemonHacker add some other\hacked code types, like
8bit Slide Code that CB doesn't support (yeah, arv3/v4 has, but is boring that you have to encrypt the codes all the times, besides CB codes are easy to handle)
