Hi @Bkg2k, sorry to bother you once again. but do you have an idea why system "megadrive" still finds and runs .chd-files, even though this file extension doesn't exist in es_systems.cfg? (see screenshot of last post)
in general it's good for me because i don't have to modify the file then, but i just want to understand why :) maybe because the chd-files are indexed already in gamelist.xml of system megadrive?
if it's because auf gamelist xml, this theory seems to be valid just for file extensions only: because on the other hand tags for cores in gamelist.xml that are not present in es_systems.cfg are defenitely ingored. for example when using core fbalpha in system mame.
