Edit: I seem to have hit a bug in the translation when using PPSSPP. Whenever I enter combat, the game will freeze entirely. This does not happen when running the Japanese copy on the same configuration. I can recreate this across several different operating systems, backend graphical systems, PPSSPP releases for these operating systems, as well as hardware configurations (have tested two physical configurations and a virtualized configuration), so I'm quite sure that the issue is in the patched ISO.
Edit 2: Repatching the game with DeltaPatcher instead of the included batch files seemed to fix this, and gave me a final output file roughly 200MB bigger than the batch files gave me (I'm currently running a 1,143,351,296 byte ISO, is this correct?). Since both the patch and source ISO are the same, I think the batch files might be borked.
Edit 3: On macOS's latest PPSSPP release, the "Hardware transform" feature will break the cursor and has to be disabled. This is obviously an emulator bug, but I figured I'd note it for others. Furthermore, disabling buffered rendering will break things, so don't. Other than that, the game runs well on the latest release of macOS on a 2017 15" MacBook Pro.
