So I'm not sure if I'm really stuck or if there is a way out; I entered the Cave of Origin and proceeded to jump on Groudons back after many battles with Primal Groudon I couldn't capture him. (either I would kill him or he would outlast me with his rest, I had no Full Restores or Potions) so I thought I'd leave his cave and come back. I used dig and bought some supplies then saved the game because I had to do something. When I went back to the Cave of Origin there was no way back into the second part of the cave. I don't think I am now able to progress. I really do not want to start again.
