I'm running Just Dance 2 off my USB HDD (NTFS format) using WiiFlow 2.2 off my softmodded 4.3 Wii. Other games work just fine. But during gameplay in Just Dance 2, I get a black screen that reads "reading disc..." then just goes back to gameplay. So there's no freeze here. It just goes to that screen frequently like its accessing the disc.
Any ideas on how to fix this?
