Pok?mon Soul Silver

Hey, new to the forum, so this can double as my first introductory post, and the thread for my question. I started to play Soul Silver today, and did a new game. Saved once, and left. Came back to continue, and after an hour, I entered a battle and the game looped the introduction sequence, where it says "____ would like to battle!" And the Poke Balls come spinning in. The spinning goes on forever, and the battle music continues to play, and nothing happens afterwards.

I'm playing with DESMUME 0.9.9, and I have sound enabled, and I don't need to input the black screen codes or any of that, because the game started fine without it. Not sure why the battle thing happened, and is there a way to fix it?

I know I'm a little late on the timing to play this game, but I felt like playing it.

Also, why doesn't this forum support accented letters?
