I'm running 4.2U, and followed the softmod guide exactly. Everything is working as it should be, I have ripped games using USB loader Gx and they work perfectly.

My problem is with Muramasa. I start the game in USB Loader GX and it goes to a black screen for maybe 10 seconds, then returns to the system menu.

I have tried changing all of the game load settings, as well as checked and updated my IOS.

Just looking to be steered in the right direction.
