NHL 2K2 Prototype Help

I recently got a second Dreamcast Dev Box and checked the contents of the HDD to find that there was a gd rom copy (prob a protoype) of NHL 2K2. There is a track 5 folder with what looks to be the correct files. I have tried making a self boot CDI image file with bootdreams but the file becomes to big to burn (and overburn, it stops at 97 percent). Is there a better way to make a self boot CDI? Any help would be much appreciated. And I will post links to the files here when I get home from work.

 

You have to shrink the files like audio or video to make a 80 min cd-r image.

 

Is that a difficult process? And what program(s) do I need to use? And how is it done? Sorry for all the questions lol

 

Before you spend lots of time to make a .CDI, did you try out the data on the devkit (just to be sure it works out of the box)?

 

How would I go about testing it on the devkit? I have everything needed and I know how to switch it to dev mode.
