well you have to be pretty dumb to necro a 4 year old thread just to promote your own work, so I wanted expecting much from it, especially not when the site states "Works fine with MAME 0.122u1 (most of roms pack are setted for this )"
but seriously, the batchfile is just a list of "del" statements with wildcards...
and hilarious entries such as
because there's no way a legitimate setname might have the letters 'ass' in them..
del cclimb* del lbowling* del gururin* del gamshara* del col*97* del cookb*
which.. aren't 'adult' games...
i'm sorry but this is the most stupid fucking script i've ever seen.
it's more a 'delete things I don't like, and close my eyes at any unintended side-effects' script.
