Hi again IMGABFDI7!
First, I'd like to ask you to stop bumping your threads or spamming replies for the sake of getting to 50 posts, it isn't beneficial or very courteous to other users. And asking if anyone is going to do something for you is technically against the rules. Please refrain from exhibiting these behaviors in the future.
Secondly, I'd like to again remind you to use a hex editor (my favorite being HxD) to view any unknown files you may have or find, as it could just be another format with a different extension.
So, looking at the file, it seems to actually be a NARC archive. Therefore, we can go and rename "mario.nbch" to "mario.narc" and load it into Tinke (which can easily extract NARC archives). Then, click on the archive in the Tinke GUI and click "Unpack" in the bottom right corner. From there, you can select the archive again and click "Extract" and choose the folder where you want the extracted files to go.
Hope this helps, cheers!
