AetherSX2 Emulator on Pi 4 Bullseye?

[PlebTech]

I've started messing about with my Pi 4 8Gb again and seem to have fallen down a rabbit hole of trying to get an AetherSX2 release for AArch64 working (not expecting it to run well, but I just want to be able to get something running). But it's not looking like a simple way to just kill an afternoon with tinkering.

My current stable OC is as follows: CPU 2200 + GPU 750 (over voltage10)

I've also manually installed Vulkan, in the process of reinstalling in case there was an issue... But even though i got the AetherSX2 app image working, and set the graphics render to Vulkan, added BIOS files and ROMs; whatever i try to run gives an error of "failed to create host display context"...

Again I am not expecting much, but I was hoping to get something jank running. Does anyone have experience with this?

Hopefully I'm just missing something obvious.
