[Issue] [Partially solved] Dolphin EX appimage fails to run

[lunelovehearn]

System Info:

OS: Arch Linux
Kernel: 5.19.1
DE: KDE Plasma 5.24.x
CPU: AMD Ryzen 5 3500U with Radeon Vega Mobile Gfx (8) @ 2.100GHz
GPU: AMD ATI Radeon Vega Series / Radeon Vega Mobile Series

Issue: when trying to run the appimage on Arch, it crashes silently and doesn't run.
expected behavior: emulator running.
Fix attempted: ran the appimage from terminal and ended with this

:
dunno why this happens, but regular dolphin from Arch repos works fine.

EDIT: based on this thread (https://itch.io/t/1888082/appimage-doesnt-seem-to-run-on-debian-12) the solution is to run the appimmage with the following enviroment variable:

LD_PRELOAD=/lib64/libgmodule-2.0.so ./ExGL-Dolphin\ V1.0.5.AppImage

The emulator will load as intended. Still I hope the issue gets fixed officialy as this is a workaround.

The workaround does not work for me.
The library was found at /usr/lib/libgmodule-2.0.so which I added to the arguments using:

LD_PRELOAD=/lib/libgmodule-2.0.so ./ExGL-Dolphin-V1.0.5-Linux/ExGL-Dolphin\ V1.0.5.AppImage
However, this also failed with the same error message:

one of the users on the discord server shared a patched version of the emulator, but you will need to install libffi7 from the aur. that solves the issue.
Edit: @Lamampis is the one who made the patched version. he shared the sources below.

Solution: run yay -S libffi7

here's the patched version:
https://www.mediafire.com/file/qxmfvytmb97zprf/ExGL-Dolphin-patched.AppImage/file
I wanted to share the appimage here, but it's too big for this website.

I still hope devs make a flatpak version of the emu and add/update the appimage with the missing dependencies.

the fix is already here.

The patched appimage was made using the instructions from the following guide:
