UNIF DRAGONFIGHTER - new board for the new dump (PCB BMW8544) 

DEBUG: finally rid out of parasite handler triggering while reading data from debugger, hope it didn't broke something
INES: some quirks to be able to run UNIF files in iNES format (there are a lot of them in the NET marked as BAD because of that), need more extra mapper numbers, probably a new range, more crc lists of roms
