This is such an obscure problem, I can't find it anywhere on Google, so I'm PRAYING someone knows a solution (that doesn't involve starting over on Plat).
First some specs: I have a fat DS (if that matters) with a Supercard MiniSD flashcart, with Pokemon Platinum on that I have been working on for quite some time.
The situation: I was entering my Wii number into the Wii settings thing on the main menu of Pokemon Platinum (so I could connect to my Wii Pokemon Ranch thing). The connection thing isn't the problem here. I entered the WRONG number, so I saw no way to go back out of the Wii settings on the game, so I did a hard reset of the DS. When I restarted and went back into the Wii settings on the Pokemon Platinum game, I saw that there are no settings, just a black screen with a loud sound loop. So I really, REALLY messed something in there up apparantly.
This is kind of an urgent thing, so if I can't get help here, I would like someone to point me to somewhere that will assist me.
(Also, once again, I REALLY don't want to start my game over...)
