While some recommend against it I've found a fresh install using ohneschwanzenegger works well if you can afford to wipe it clean.

Is there a list of what VC doesn't work via USBLoaderGX emunand? Is it known why they don't work? I've been trying Last Blade 2 and on occasion it seems to work but usually it freezes. Sometimes it just goes to a black screen which I can exit out from.
4.1U
IOS53 v5406 w/ trucha
cIOS 249 v15
WiiFlow or USB Loader GX or uLoader 3.1
NTSC iso
Game starts can play for a little while then freezes. Music will stop and if you die or end the level it freezes. What am I missing?
