It means the hardware isn't fully understood and it's not known how to dump a certain rom. You can still play the game though.
It's nothing you can correct on your end unless you possess the knowledge or skill to improve the situation.

It means that one or more ROMs/CHDs have not been correctly dumped

Others already explained, but just for extra detail to mention some of the pcbs might have parts that the contributor might not have a specific adapter to handle extracting data/reading from a particular component.
>games like mercs....have that message
Using Mercs as an example.....
--
src/mame/drivers/cps1.cpp
ROM_REGION( 0x0200, "cboardplds", 0 )
ROM_LOAD( "c628", 0x0000, 0x0117, NO_DUMP )
ROM_REGION( 0x0200, "bboardplds", 0 )
ROM_LOAD( "o222b.1a", 0x0000, 0x0117, NO_DUMP )
ROM_LOAD( "lwio.12e", 0x0000, 0x0117, CRC(ad52b90c) ) // pal verification required
ROM_REGION( 0x0200, "cboardplds", 0 )
ROM_LOAD( "c628", 0x0000, 0x0117, NO_DUMP )
ROM_END

some pcbs might have GALs or pals that a contributor might not have a specific reader to handle reading data from the component. In fact some are protected and not really readable whatsoever. As already mentioned, these are out of the hands of most users unless someone actually does have a pcb and can send to someone that has equipment that can read the data.
Over the past ten years a number of the Cps1 pcbs have been redone in which there have been a lot of rom fix updates and more pal and gal components being read so the cps1 emulation progress has improved a fair amount.
