DAPHNE supports a ROM system similar to that of MAME. You can create "game name" directories and put uncompressed ROM images inside them or you can just put a .ZIP file containing the rom images in this directory. Example, for Dragon's Lair, you could either have: ./lair.zip OR ./lair/dl_f2_u1.bin ./lair/dl_f2_u2.bin etc ... The daphne_log.txt file (create when daphne runs) will tell you which files DAPHNE is looking for. You should use it to figure out where to put files if you are confused.
