Title: Mame rom information
Post by: zerocle on September 15, 2006, 05:02:34 pm

I just have a quick question, how do the front end's get the rom information(game name, required files, game type, controller, etc. ) from the rom files? is it a database file that they just reference? or a mame function?

MAME ROM information comes from MAME itself.  Front ends will run MAME and pass a commandline parameter (-listxml), which will output an XML file with all the info.  Front ends then parse this information and normalize it with its list of available ROMs.

Before you ask, other emulators get their data from clrmamepro dat files, which are based on listinfo, which is what listxml is also based upon.
