I'm using a supercard mini sd version 1.7 with a 1GB sandisk sd mini. I got Yu-Gi-Oh! Duel Monsters World Championship 2007 rom and patched it with the latest supercard patcher. I then run the game on my ds. It starts out fine in the beginning. But after i enter a free duel with a CPU and go back to the deck construction menu, my ds starts to make strange noises. The speaker was just static. What should i do to fix this problem. Please help. thank you!
