So I've been trying to burn original xbox games onto DVDs but to no avail,

I've been using Mac OSX Yosemite 10.10, with Keka to turn any bin/cues into ISOs and Disk Utility to burn them but no luck. I had a feeling I was doing something wrong so I checked this link but...

This method only seems to work for Windows based PCs, are they any ways to do it for Mac users? I've been trying to burn Metal Wolf Chaos and Dino Crisis 3 to an already modded xbox but it doesn't even read them.

What am I doing wrong exactly?
