Unfortunately none of us knows which methods you tried. You seem to have some unusual views on how Windows works. May be worth asking someone technical to explain you things. Unless it's a matter of faith rather than knowing facts.

But I agree the central registry which Windows introduced is stupid. Its introduction broke many paradigms and tainted
that OS for ever. Fortunately every other OS keeps configuration of each application in separate file or folder. There are many streams with both DK1 and DK2. So people have no problem streaming these.

For windowed mode - the game does have a config switch for that, it's just not within options interface.

And if you don't want to reconfigure the game, or that doesn't produce the results you seek - you will need some kind of DirectX (D3D in this case) hook library, which modified the graphics calls the game does. There are multiple tools for that - recently dgVoodoo2 is quite popular.

One usually tries to reconfigure the game first though - 3D hooks are a complex thing, with a lot configuration options and dependencies between them.

If all fails - serious streamers tend to use hardware encoders.

Could you elaborate on what you mean by "reconfigure" here? Or point me in the direction of a beginner's guide on the subject? Thanks.

How I find things:

I looked into the game folder. I searched for config files, found none. I then searched in my user folder, also found nothing. Then I grepped the binary:

[pre]
# strings DKII.exe | grep -i config
QSWaveMixConfigureChannel
Configuration
HKEY_CURRENT_CONFIG
[/pre]

From the last entry, I figured the config is in windows registry. In that registry, applications usually go into "software" key:

[code]
# strings DKII.exe | grep -i software
MMX Software Renderer, by Martin Griffiths, 1998/9 (fast sub-pixel triangles huh?!?!)mail me at mgriffiths@griffster.demon.co.ukWVRSUQ

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\DirectXDrivers
HKEY_LOCAL_MACHINE\Software\Microsoft\DirectX

software\Electronic Arts
[/code]

So I learned who creates software renderer for the game, but also from the last two lines - where the registry keys for the game are.

Now I opened the game in a disasembler and searched for that. I got:

[code]

While this is not easy to read, it lists all names of the options within registry, and final branch name.
Now I opened `regedit` on a machine with DK2 installed, and searched for the names. I found this:

```

This forum is primitive - I can't seem to make preformatted block.. sorry for that.
Also editing my previous post does not work. Hopeless.

Try going to keeperklan forum - it works. And you will get help from fans there.

I feel this is a good moment to post the Keeperklan Discord link again: https://discord.gg/zKTjfDh
