Mario & Luigi Bowser's Inside Story [US]

Hi, I'm having a problem with the Bowser's Inside Story US ROM. I'm running it clean on DeSMuMe and, whenever I go to the first Midbus battle, the screens shift half of the battle to the top and bottom screen, as in, you see half of the scene on the top and the other half on the bottom. After Fawful finishes talking, the screens return to normal but the game freezes.Can anyone help, please?

Is there anyone that can help me, please? :(

hmmm.... which version of the emu do you have?

Are you using the latest version of DeSmuMe and are you sure that you have a clean ROM of M&LBIS?
