if it is so difficult, then it can be done using the PowerToys Hosts File Editor

ok not sure if this will help anyone else but this is what worked for me (and I fully realize this was due to me not being very programming savvy):
When you paste the lines just don't put the hashtag symbol in (also possibly that i only put in the lines for stealth inc 2)

any idea if this still works on windows 11? I tried all of the comment suggestions and I couldnt find any levels in the game. When I run the bat file normally it just leaves the powershell window open but doesnt seem to be doing anything. When i run as admin it immediatly closes again even with the pause and noexit commands added to the batch file. either way nothing is showing up in game

Would you be able to share how you do this? reason is i would like to host a server for another dead online game named 'Wickland'

working "authenticate_ps4.php.ps1":
function POST-authenticate_ps4.php {
Param($Context)

$issuer = $Context.Request.QueryString.Item("issuer")

Write-Host ("Issuer: $issuer")
Write-Host ("Content: " + $Context.Request.RawContent)

"0"
}

a little more detail:

Заработало! :) Ачивку получил! Спасибо.
work authenticate_ps3.php.ps1:

function POST-authenticate_ps3.php {
Param($Context)

Write-Host ("Content: " + $Context.Request.RawContent)

"0"
}

I mistyped function names
https://github.com/heatray/stealth-server/commit/948597e8e95c1576505249f99b21db7480dd52df

after restarting the game on the console and removing the "0", performance is restored; apparently something breaks on the console.

good news :)
I made many attempts (more than 50), additionally tried "connected, allow, successfully, valid, accepted, ok, continue, true"; and finally tried "0" and the server crashed!

I started the server again and tried to send just double quotes (as it was originally) and the previous option, but the server crashed at the first request! using the screenshot, I caught the action and text of the error before the crash:
