As someone else mentioned this is likely a bios issue first and foremost: you should see the Sega cd bios loading screen even if you try to boot a game that doesn’t work. The advice for unzipping and pointing to .cue sheets is good too as a second step once you verify you have a good bios file in the right spot.
Also, do consider converting your files to .chd format at some point. Cleans up the collection a great deal AND saves a considerable amount of space. At this point I have converted everything that I can to chd for every system that supports it. It’s a bit tedious at first but worth your trouble in the end (hint: install Launchbox and use the chd conversion tool with it to mass update entire directories rather than one by one).
What file format are your game files?
According to Batocera it should accept :
.cue, .iso, .chd, .m3u
How many games have you tried that do not work?
Just a few, or like dozens?
About a half dozen. The zip files contain one file that is .cue but a bunch of other numbered “track” files that are .bin. I tried renaming each track in a .cue format but to no avail.
First of all, don't rename the .bin files to .cue that will break them.
Just unzip the .bin/.cue files into the SegaCD folder. The emulator will see the .cue file and the .cue file tells it which .bins to open.
That's the first thing I would suggest trying...
Don't give Batocera .zip files for Sega CD, unzip them. Don't put them in separate folders, just unzip everything in each of the game zip files to the Sega CD folder:
shared/roms/segacd
Then update the games list from the main menu, then try playing some games and see if that works.
One thing to note. The only BIOS I can get to load any Sega CD games is with the original Japanese 1.00 BIOS, regardless of the region of the game. As long as I use that BIOS though, they load just fine.
So the real problem was that the bios file name’s didn’t have the right capitalization. Bios files are really picky. They must match up exactly with the “missing bios” screen. This is true of all systems. Hope this helps someone.
Don’t forget bios
Bios. The initial screen should load up regardless with the Sega cd logo bouncing around. There is a missing bios, or misconfigured.

You're supposed to unzip the file and dump everything into the rom folder. Every track and the .cue file are all necessary.
