Yeap, I ended up looking there and there were hints to use certain proton versions buried in the reports. Will update my OP now with the solution. Thanks!

I tried swapping the files so that the sh3.exe.Backup (original file) was the one being run and the patched version was renamed to something else and it still does the same thing. Could it be something else causing the crash? How can I track it down?

I have steamtinkerlaunch setup to use proton-9.0-2e. How can I force it so that I can test it out?

Edit: Just saw in the steamtinkerlaunch options for proton there is a check box for “Force large address aware” and it is enabled. Weird why it still crashes though

SteamTinkerLaunch worked like a charm! Here’s what I had to do to get it to work, for anyone who stumbles across this post:

• Install the package pacman -S steamtinkerlaunch
• Run the command steamtinkerlaunch compat add to initialise it
• Add it as the required compatibility layer in the game I wanted (SH3) then restart steam
• Launch the game - the steamtinkerlaunch window opens. Click on the MAIN MENU button before it launches the game
• From the new steamtinkerlaunch window that opens, click on “One time run”. This opens yet another window
• In the field “One time command” navigate to where I had LSH3_2022 downloaded, and select it
• Click on RUN COMMAND
• Follow the install steps in the LSH3 manual
• Repeat the steps related to “One time run” again but this time select the JSGME installer, and go through that installation
• Launch JSGME again using “One time run” and enable any mods I need (although LSH3 has a 1920x1080 widescreen mod included, this doesnt seem to work at least on my setup. I had to enable the Ahnenerbe WideGui 1920 x 1080 Final mod)
• Launch the game. It should work.

So far I completed the first training mission to make sure most things work. Hopefully there aren’t any issues further on down the road. Thanks for the suggestion, I had no idea this tool existed, but now I will probably be using it quite a bit!

Ok so even though glibc is quite deeply integrated at the system level, its okay to replace it with the eac version(?). And what about the glibc-eac-locales? What are they for and why is it necessary to manually install them?

Yea, I learned my lesson about -bin packages a while ago with electron or something related to it. When I tell you it was taking several hours to compile and I was getting worried because while I dont have a supercomputer its on the high-end for an average user… xD I immediately grabbed the bin package right after that update finished.

Do you mean you removed the non eac version of glibc?

I poked around in its settings and it seems to have that feature

I set it as my default search engine on my mobile, and will check it out for some time before committing to all my devices

Ill check startpage out! Also an interesting blog post regarding kagi. Ive never used it in the past, but now i definitely wouldnt ever even consider it.
