Any way to add CD based games to the cross media bar?

When you scan a directory of ROMs, RetroArch adds a nice list of all the games to the cross media bar, grouped by system name. So I have long lists of Mega Drive, SNES, NES, PC Engine etc. I can’t get it to ever add any CD based games though (except for Playstation). I’ve scanned directories of PC Engine Super CD-ROM, Sega Mega CD, and Sega Saturn, but they’re never added. I can load these files (BIN/CUE files) manually and the games run fine (mostly, Saturn emulation is still pretty rough) , it’s just a chore to have to navigate through a long list of directories every time when other systems get a nice easy to access list.

Is there any way to fix this?

Thanks all.

The easiest thing to do is to use a playlist script or utility. There are a number of them floating around on the forum.

Perhaps it needs some modification depending of the way your folders are.
