Hi Dreamcast Developer here.
I patched Metrowerks Codewarrior for SuperH & Sega Dreamcast with the IDE 6.0 and some files from Codewarrior Pro 6.1 And it compiled too! Now Codewarrior is no longer buggy or crashing, slow and works faster better, yes It has been tested on Windows 10, I was able to compile code for SH-1, SH-2, SH-3, SH-4, took trail and error but I got it!
I also use Codewarrior for SuperH Development, besides high-performance Embedded Workshop for SuperH microcontrollers.
I use Codewarrior Pro 6.1 to develop software for Windows, Mac(PowerPC & M68K), and to develop Plugins for Codewarrior IDE.
It's now uploaded on archive org for anyone to tryout the updated version of Codewarrior for dreamcast & superh, I might make a sega saturn version with inhouse plugins developed by me at some point but who knows.

I'm sorry for my lack of knowledge, what's the purpose of this tool please ?

Allows you develop code for dreamcast and debugging also has support for a overlay code system. I tested it and was able to build a simple dream cast program.
It's a IDE, Compiler, Debugger for Dreamcast & SuperH development.
I also have Codewarrior for ARM too. I got the tools from ARM Support.

I found the missing overlay support files for codewarrior in a older codewarrior version that was missing not sure why it was removed haha
I also found the missing examples folder for codewarrior dreamcast version that was talked about in the targeting dreamcast pdf doc
I also found the missing extra codewarrior help doc files but in pdf format
I have now updated the codewarrior patch for superh & dreamcast on archive org

Here's what the Metrowerks Util Lib for Overlay support missing file looks like
It was a standard c lib for supporting the Metrowerks Overlay Module System
