OK, I’ll rephrase my question. What is required to get Doom to run?

I’m not someone that expects people to do all my work for me. For example, in the few hours I’ve been using RetroArch I’ve learned what is needed to convert ECM files and APE files to get another game that I own a legitimate copy of to work. I am just really struggling with this CDDA issue.

I already have a .bin and a .cue file for Doom. Are the CDDA files in the .bin file and need to be extracted somehow or do I need an image that was prepared a different way in the first place?

Edit: Nevermind, I’ve got a working version now. I still wish I understood a little more about this issue in case I have similar problems in future.
