PS VITA PCSX Rearmed: Zanac X Zanac compatibility

Anyone else having an issue with Zanac X Zanac freezing during the load screen right after the main title screen? This game is one of the best but runs like crap with the official PSX emulator on the Vita. I would hope since it’s a 2D game that it would run faster via retroarch just like all my other 2D psx games do but it keeps freezing. Any thoughts?

Not working on Android either.
I think it’s an upstream problem, I saw it mentioned by different people on forums.
