I try 3 games Final Fantasy VIII, XI and Metal Gear Solid with CD Access Method (Restart) set to synchronous. All games are with .M3U files and .CDx extentions . I use the new disk control menu.
-All games are booting fine
-I start all games from CD2 and when the game ask for CD1 the changes was succesfully
-I use a save file in FF 8 and when the game ask for CD2 the change was succesfully
-I try 3 times to change the disk without the game ask for this (it's not a normal condition) and i had a lock-up and 2 times a black screen(i choose reset from retroarch to get out from this)
Generally, the fixed version working fine without the previous lock-ups during exit and during disk swapping.
Thanks again!
