For MAME, Mala copies the rom name and real name from the xml over to the gamelist file.
I'm not sure if it maintains two separate entries like that for the other emulator gamelists, but you can convert the mlg to a text file and see.
Use mlgconverter.exe from this thread:
http://forum.arcadecontrols.com/index.php/topic,101104.0.htmlIf there are separate entries for the rom name and game name, you can change it then convert it back to a mlg file.
I'm not aware of any xml type files for the other emulators.
I'm using SGT's multiple emus in one list workaround stickied at the top of this forum.
That makes them all show up in one list and pulls the info from mame.xml regardless of emulator.
It's a whole nutha level of setup though.
