Okay, so I was in the Fight Area on Platinum and there are these two guys blocking each path to the Resort Area, Survival Area, and of course, Stark Mountain. One of each pair asks me if I've been to the Battle Frontier, which I have several times, and the other asks me if I have a National Pokedex. Now I know that you have to have filled the Sinnoh Pokedex to get the National on Platinum, but I have a full Sinnoh Pokedex on Diamond and Heatran is in the Sinnoh Pokedex, right by Cresselia. I want to get Heatran, so I have to get to Stark Mountain. But those guys won't let me through to Heatran until I get a National Pokedex, and to get the National Pokedex, I need Heatran, so I need to find a way to get to Stark Mountain, but the guys won't let me through until-Head explodes. Heh, just kidding. But seriously, how do I get through? I also wanna catch those alleged level 100 Magikarp in the Resort Area, so please help!
