I found 2 bugs:
The first one, the one that is keeping me from advancing, is in the first gym, the last poison combination, it says it should be Orange, White and Teal. I am only getting the orange one right, and every other combination I try says it is not correct, how to proceed?
And the second is right after we escape with Malia/Melia (sorry, I forgot the name) and her togepi from the forest, (Zeta and the gyarados stuff), if you go back to the forest, before entering in the professor's lab, and then enter in the cave and go out the cave, you kind go "back in time" when team xen is there and can fight zeta again, but after you are sucked by the gyarados the screen goes black, but you can still move and stuff.
Edit: about the first bug, I've looked the combinations in the painel and stuff, and I am trying to do the combinations like it shows there.
