Setup of Advanced MAME Launcher

Thanks for the reply ! (clearer than the answer off the copyright freak !!!)
Is there no executable for the internal emulator ?
I also noticed that the internal Mame emulator open some games zip file as a folder (Pang.zip), others the game starts with no problems (3wonders.zip).
Any idea why ?
Advanced config XML is OK and no association with compressed files in osmc .
