The PV drivers currently expect any software loaded to be either 8K or 16K. As a temporary solution you could pad the ROMs out to 8192 bytes with zeros.

As would a original hardware solution an image would need to be on an eeprom matching to traditional power of 2 sizes and a rom image should be no different. I'd say the image should comply and that MAME is not at fault (simply ensuring your image you provided is a valid size). It isn't unreasonable to expect.

While the recording seems to be done on original hardware - we don't know how the image was presented to the hardware.
