media_playlist_index. libretro-uae adds the A600OG and A500ECS model
tags, the floppy, HD and CD defaults stay A500, A1200 and CD32.

87bcc96b. Each cited block was compared with the code at the new pin.
The region and BIOS logic is unchanged, only line numbers moved.
mame2000, mame2003 and mame2003-plus carry a DAT their code moved past. Their parents and BIOS sets now come from src/driver.c and src/drivers/ at the pin, named by the src tree sha. The DAT is still read to report gaps. FBNeo DATs are read one namespace each, console sets keyed by driver. A BIOS with no dumped ROM is no longer listed.
The games index now names, per arcade core, the game sets that load no
BIOS set and every BIOS set, so a set on a card the DAT does not know is
told apart from one that needs nothing. Each board default core of a rom
folder gets its own fallback set, and index.json maps every folder name
a setup uses to its systems, for a games folder on a computer.
