And why tracks starts from 2 not 1. First track is system meta data?

The first track is the iso9660 filesystem, in this case containing the game data files (it's just empty in the "music only" image).
Most games from the late 90's that included music used these mixed-mode discs, where the first track is mode 1 (CD-ROM) and the rest of the tracks are mode 0 (CD-DA) audio tracks. That way the music can be played by the drive's audio playback hardware without the CPU load of decoding, say, MP3 files.
If you put such a disk in a CD player it will actually try to play track 1 as audio... With somewhat unpleasant results. Your ripping software is smarter and will ignore it.

It's the same on any OS, you learn what software you like by trying it out or by word-of-mouth. You find windows easier because you have more experience with it.

This cdemu its a red-eyed bloody mess for me. Compile and installing  and run. Its all very difficult.

Well you did pick the hard way, compiling it by hand in your home directory. Installing from the deb-multimedia repos is pretty painless (that's how I install it), and using dpkg to build a .deb package from the source shouldn't be much worse.
It's common practice on linux to install applications system-wide using the package manager, so it's not surprising that going against the grain will make things difficult. Had you built and installed a .deb package, it should have set up the udev rules and all that for you.

Of course if debian actually shipped the damn thing in their repos, there would be no hassle whatsoever. I really don't get the complete lack of interest from the maintainers on this particular package TBH, especially as the cdemu devs have gone so far as to include all the needed files already.

how to know that for mount needed all 3 files *.img, *.ccd, *.sub but mount needed only *.ccd?

Understanding of CD formats, experience, and a little guesswork. Also extrapolation from the bin/toc example in the cdemu manual, where it demonstrates giving cdemu only the .toc filename and it figuring out loading the matching .bin by itself.
.ccd, .cue, and .toc are all "table of contents" files that define how to read the matching .bin or .img, it's pretty logical that you'd need to load that first. Simply opening the .ccd as text should make it obvious what it is and why you might need it.
.sub is subchannel data, and IIRC it's optional unless the disk actually uses a subchannel. Subchannels are most commonly used for supplimental data such as CD-TEXT (track titles), pre-emphasis data... or for copy-protection bullshit.

Don't use deb.multimedia.org, that place is poison for a clean De{bi,vu}an system.

Just download the cdemu tarball from upstream, unpack it, then run debuild -us -uc in that directory to build the .deb. The tarball contains a functional debian directory.

A blanket "don't use" is a bit FUDish for me TBH. Like any 3rd party repository, the magnitude of the mess is largely dependent on what one installs and the sensibility of one's pinning.

Set up package priorities properly (i.e. everything but the specific packages you want pinned to -1) and there's no harm in installing a few things from deb-multimedia... As long as you avoid core media library replacements, they will most certainly make a mess.
Nothing a little apt-foo can't fix mind, but unless you really need, say, ffmpeg compiled with all the codecs possible, it's a situation best avoided.

Alternatively, simply installing the individual binary packages works fine as well, since they don't depend on anything else that isn't in the debian/devuan repos.
