Hi, I am trying to make beetle psx working in retroarch, but it fail to start.
I am on Archlinux laptop with
lspci | grep -e VGA -e 3D
00:02.0 VGA compatible controller: Intel Corporation UHD Graphics 620 (rev 07)
01:00.0 3D controller: NVIDIA Corporation GP108M [GeForce MX150] (rev a1)
I tried some stuff, but nothing work…
