Trouble running Ni No Kuni (BLES-01555)

Hm, I'm having some trouble with the renderdoc capture process. I believe I've set it up properly according to your instructions, and principally it appears to work. I can capture frames from RPCS3. However, as soon as the freeze occurs, it won't capture anything. Neither with PrntScr, nor via the "Trigger Capture" option from within renderdoc.
