If you have the 0.202 MAME romset then use 0.202 of the MAME emulator. Also depending on the romset type you have you may be missing the bios files, the non-merged romset contains all the bios files inside each game zip, the other two merged and split may not have those bios files in the romset at all.
I can confirm that all the 1940 series do indeed work providing your romset is good, are using the correct version of the emulator and you have the bios files.
