advmame + mamewah / gamelist problem

[littlecharlie]

Hi everyone,
I can't generate a game list with the actual name of the games, only the rom's name
I remember I achieved to generate a list with mame command line version and mamewah, (using mame.dat or mame.xml , can't remember exactly which one is useful) I've tried to make the same thing for advancemame but it doesn't work.
Someone knows which generate_list_method is useful and if there is a file needed (kind of .dat .xml or whatever ...) ?

thanks!!
