Nero and DC question

I had read a document on how to burn a DC game. It was a bit different than some I have read but many others say different things. This one was for Nero alone so I followed directions. I used these programs.

Fireburner 1.06
ISObuster
Newfile
and Nero 5.0.3.5 (newest)

The main files that came from the download after extracting the ZIP were
DOA2.ISO
DOA2.cue

Then after that I extracted the ISO...was that right?


I might have used Disc Juggler for a step but I can't recall because my other comuter isn't up right now.


The file didn't need Winrar because it was already 1 big file which I prefer because of cable and the place I get the files are much easier to use 1 instead of 15 or more files.

I used Nero for the Boot disc and it worked. By the way, the DC isn't mine, it's someone I know who used my disc so I am not speaking from experience exactly. After he told me the boot worked, he said he put in the CD-RW (Maybe the problem,maybe not)

I want to know what file goes onto the disc because the disc I burned has many, many files on it not just 1 single image file. Is this bad???
