CS 1.6: ReHLDS not working

[sic6SaNdMaN]

Hi.

So I switched from a Raspberry Pi 4 to 5 (4k pages kernel).
On the 5 exagear isn't working anymore, so I went for box86 and box64.
TeamSpeak-Server is running fine, np with that.

Than I wanted to switch my CS 1.6-Server, too.
But this one wouldn't work.

I broke it sown the last few days:
A vanilla hlds_linux will run just fine.
But when you install ReHLDS (and you want this installed ;) ), then the server dowsn't fully start anymore.

I have some more mods and stuff, but they aren't the isse. It starts, when you switch from vanilla to ReHLDS.
That's done in just one minute:

• Get it from https://github.com/rehlds/ReHLDS
• extract it
• copy over the contents of the "bin/linux32"-folder into the hlds-folder (not into a mod folder, like cstrike)
  That's it.
  And now the server won't start anymore. "Log"-messages at the end of this post.

So... what can I do?
On the GitHub-page there is this mentioned:
ReHLDS binaries require SSE, SSE2 and SSE3 instruction sets to run and can benefit from SSE4.1 and SSE4.2
Is box86 able to emulate SSE3?

Any help appreciated.
Thx.
