are you using a frontend or straight off the mame32? as they are talking about the MAME (command line) version which is easier to modify, and if you were using a frontend, then can set it load the CL Mame instead, that item from Ultimarc I dont think would solve your problem, try getting the latest .126 build of CL MAME and just dumping a couple of roms into the folder and test it and see if it works for you, then if so, grab a frontend such as MAMEWah, Mala, GameEx and play
