Description

Sorry for my english.
I managed to use a MAME 0.78 romset with a specific playlist and 2003 plus emulator.
All games I tested work. NeoGeo games work as well.
By the way no thumbnails and only short rom names.
So I downloaded several dat files, MAME or FinalBurn
When I load the playlist with dat, I have many correct names and thumbnails, but NeoGeo games stopped to work...
Where is the error?

OS
Mac Os Ventura

Thank you a lot
Francesco

Research direction

Start by reproducing the reported setup on Mac OS Ventura: a MAME 0.78 playlist with the 2003 Plus emulator, then load a playlist with MAME or FinalBurn DAT files. Compare the naming and thumbnail behavior with NeoGeo playback; done means correct names and thumbnails appear without breaking NeoGeo games.
