Gaming Super Smash Bros Brawl on 4.2 using NeoGamma?

[Avalith]

I recently softmodded my 4.2 Wii using the Bannerbomb approach and used NeoGamma 0.3 r6 IOS249 as my backup launcher. It won't read from discs for whatever reason (probably because I'm using TDK discs, but that part is irrelevant), but it reads everything from my USB hard drive perfectly... until I play Brawl. It will let me go into Adventure Mode and play the first battle, but after that the opening cutscene just keeps replaying with no way to stop it short of returning to the Wii menu. I'm just curious if this is because I used a DVD5 version of the game despite WBFS Manager inflating it to 6.93 GB or however much it was or if it's some sort of AP I need to apply a patch or something for.
