Sony Xperia Z1 game won't start black screen after nintendo logo

Some people are working around the issues by using the JITIL CPU recompiler, which doesn't have any known bugs but is slow; taking a save state; then loading the save state under the JITArm. Another thing could be that they made the video on a version without the CPU bugs. It's mostly just fiddling with options right now while the CPU core is under development.
