Hmmm i understood, i had some chaos in my mind, also a dummy empty azumanga.zip works, it's just matter of provide the right name in the command line

Does it exist an azumanga.zip, brddown.zip and so on? In the Demul07 complete set i downloaded there was nothing of similar, just the CHDs, so at first i had to set some .bat to make them work cause frontends picked the name of chd instead of the game. Now i found that also renaming chd works. A little confusionary people at demul team or who made the fullset

I've tried and in effect if you rename gdl-0018.chd to azumanga.chd demul is able to launch without doing tricks........ Such a mess they don't rename the chd according to demul request.........

I used these command lines on emulationstation for DEMUL0.7 and they works demul.exe -run=cave3rd -rom=%BASENAME% demul.exe -run=hikaru -rom=%BASENAME% demul.exe -run=awave -rom=%BASENAME% demul.exe -run=gaelco -rom=%BASENAME% demul.exe -run=naomi -rom=%BASENAME% Where %BASENAME% = romname without extension .zip, for atvtrack.zip demul.exe -run=gaelco -rom=atvtrack For Naomi GDrom base i had to use a batch file cause the GDrom file has a different name from game it represent, so unfortunately you have to make a batch file for every game (maybe renaming GDrom image with the game name would work but haven't tried).
