Seems to be incompatible ATM. I suppose you'd need time wait for this to get reviewed and see if it fixes any issues.
Well the compiling now works, But as wwylele mention, just casing citra to crash while game loading, but someone mention they got Sm4sh to work with a save file.
--------------------- MERGED ---------------------------
Weird. The computer I'm using(not mine) still can't load Citra properly.
All builds(except for 2 years old builds) won't display properly.
Again, specs:
Intel Pentium CPU G3260
64 Bit
AMD Radeon R7
Edit: To my surprise. I'm not the only one who have that problem.
When I disable Hardware Renderer, everything is visible.
Ofc, people including Devs said that "Citra is experimental". But I don't see that's the answer. In my speculation, I assume that any AMD Radeon GPU doesn't run Citra well.
With further proof from other people from Citra Forums, I can tell that the GPU is the case. Now I tried updating the driver and still won't work.
Citra just to weird with hardware, either has to be good with good opengl, maybe that video card not much open gl version might be casing your issue..
