MAMEUI64 0.152, odd, the parent and all child versions of that ROM are listed green for working condition though it does say the video emulation isn't 100% accurate.
which version of the ROM are you trying to use? if it's any of the child versions (midway new, midway old, old, older) then you need the parent ROM as well as those. should be able to just download then drop the zip file in the ROMs folder (don't unzip them) > refresh the available list in the emulator and they should show up as playable.
off topic but i just noticed all of the donpachi games are now green in the listing. i can finally play Dai-OuJou and Bee Storm without any major issues. come, DonPachi (giant bee), let's dance again.
