Mame rom information

(1/1)

zerocle:
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?

screaming:
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.

Howard_Casto:
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.

Wow thanks for the quick replies guys, that helps alot, I had gone through the mame command line options and I hadnt been able to find it. Thanks for the help :-)
