Extract your game, it won't run from a .zip/.7z.

Extract your game, it won't run from a .zip/.7z.

Unfortunately this didn't solve the issue. The exact same "Illegal instruction" error occurs when booting a zip, a bin/cue or iso.

[bslenul]

OK :/ And with the extracted game, logs are the same or do they go a little further?

[0yz]

Seems like the same output. Meanwhile I installed other bios files but that also didn't help.

Yeah no change indeed :/

Does it work with older versions? Like if you grab the core from the RA 1.9.12 cores package (https://buildbot.libretro.com/stable/1.9.12/linux/x86_64/RetroArch_cores.7z) or from 1.9.11 (https://buildbot.libretro.com/stable/1.9.11/linux/x86_64/RetroArch_cores.7z)?

I've tested from 1.9.11 to 1.9.13, retroarch with pcsx2 core can't boot any roms on Ubuntu 21.10 .

What's your CPU? Does it have support for AVX2? Because that's listed as a requirement in the documentation:

https://docs.libretro.com/library/pcsx2/#requirements

[bonswouar]

@realnc Is AVX2 support really required? According to the official PCSX2 wiki it'd be recommended, only SSE2 support is required.

I'm personally having the same issue, but I've just noticed this difference between Libretro & PCSX2 documentation. Thus I'm curious if there was any way to make it work without a CPU supporting AVX2 instructions?

[azw71]

I can confirm that AVX2 support ist required under linux. My Jasper Lake pentium N6005 didn't work with the official flatpak version 1.10.3. Manually compiling libretro-pcsx2 without avx2 resolved the issue for me.

@azw71 would you be so kind as to share your build recipe?

stay tuned, I'll look for my shell history and post some details here within the next week
