When I generate a romlist for MAME using extras (Catver.ini, players.ini, mame.xml, etc) I get a list that's duplicated. The first set of roms is correct, then at the end there's a second set of the same roms, but missing all of the information. It looks something like this:
1943;1943: The Battle of Midway (Euro);Arcade;;1987;Capcom;Shooter / Flying Vertical;2;270;joystick (8-way),joystick (8-way);good;1;raster;;;;2;;;;
... (a bunch of roms in this format)
1943;1943;;;;;;;;;;;;;;;;;;;
... (a bunch of roms in this format)
Any ideas?
