Black screen (can hear sound and see terminal output)

Version: rpsx #8af932d
OS: macOS Monterey 12.5 (21G72)
Hardware: MacBook Pro (13-inch, 2019)
GPU: Intel Iris Plus Graphics 655 1536 MB
PS1 BIOS: SCPH1001.BIN
Game: Klonoa - Door to Phantomile (Europe)

I can hear the sound and see output in the terminal which looks normal, there's just no visuals displayed as seen in the screenshot above, the screen is always black. I think this may be OS/GPU related so I have included my GPU above, I understand this may be a tricky one to solve without the same hardware/OS configuration. I might try giving it a go on Linux at some point.

Here's some of the initial terminal output if it helps:

I've tested this game just now and can confirm it's playable on my end using Windows 11.
It might be something to do OpenGL support on macOS, but it should still work as it's only drawing the video output onto a quad.
