Works well on latest muvm-0.3.1+FEX-2502..

Hi @n3ph , I'm trying to launch Project Zomboid on Asahi Linux via Steam. It crashes at startup. Sometimes the loading begins and sometime only black screen. The most far it goes is to "game loading" then crash. Does it still work for you ? Thanks

[n3ph]

I haven't tried it in a while TBH. No time ATM. Do you use FAR 42 with recent packages?

[BenChich]

Yes, I use Fedora Asahi Remix 42 with recent packages (fex-emu.aarch64 2505-1.fc42 , muvm.aarch64 0.4.1-1.fc42).

Successfully started tutorial today (app-emulation/FEX-2508.1 + app-emulation/muvm-0.4.1)

Finally saw a stack trace:
