I've got a US 3ds xl on 9.2 sysnand and 10.7 emunand using rxtools. I have no problem with the basic 3ds titles, and even have GBA titles running successfully by installing to sysnand and/or emunand. However, if i try to install any custom vc title on either sysnand or emunand, I get a black screen. No error. It just freezes the console and I have to hold down the power to cut it off. What am I doing wrong?
