if you are asking to remove roms not compatible with that specific emulator, well, you will most likely will need to try one at a time... and delete them..
maybe you can record the tv with your phone or take picture of the non-working rom to keep it easier finding which ones are not working so you can delete them later
if this is teh case, trying them on other emualtors is not effective because they will very likely work.
but if you think your roms are broken (for example by a bad download, or bad copy to your card) i would suggest to re-download the sets with roms prooved to be correctly dumped. not sure if no-intro sets are available in the nes and snes games..
