It reads every ROM, the OPNA rhythm samples and\nthe floppy drive sound samples from one ROM directory.\n\nThe ROM directory is $QUASI88_ROM_DIR when set, else the rom folder under the\nQUASI88 home (src/file-op.cpp:444-464,521). The home is the working\ndirectory when it holds quasi88.ini, else $HOME/.quasi88 (src/file-op.cpp:\n494-516). The -romdir option replaces it (src/getconf.cpp:282-290,529). The\nCMake ROMDIR setting becomes the ROM_DIR macro (CMakeLists.txt:31,38), which\nonly fills the help text (src/help.h:214) and does not move the search.\nPaths below are relative to the QUASI88 home.\n\nload_rom tries each name of an entry in order inside the ROM directory and\nstops at the first that opens (src/memory.cpp:175-219). A missing ROM is\nfilled with 0xFF, and a short one is padded with 0xFF, so the emulator starts\nwith any ROM missing. The machine model comes from byte 0x79D7 of N88.ROM\n(src/memory.h:44, src/memory.cpp:503), and BASIC_AUTO, the default, boots V2\nwhen that byte is \"4\" or higher and V1S otherwise (src/initval.h:53,\nsrc/pc88main.cpp:2755-2761).\n\n-compatrom FILE loads every main and sub ROM from one P88SR.EXE image\ninstead of the separate files (src/getconf.cpp:535, src/memory.cpp:341-369).\nThere is no default name.\n\nWith -samples (off by default, src/snddrv/quasi88/mame-quasi88.cpp:506-510,\nsrc/snddrv/quasi88/SDL/audio.cpp:91-94) the drive sounds motoron.wav,\nmotoroff.wav, headdown.wav, headup.wav and seek.wav are read from the ROM\ndirectory (src/snddrv/quasi88/mame-quasi88.cpp:101-108,1085-1127). Any mono\nWAV is accepted (src/snddrv/quasi88/mame-quasi88.cpp:92). QUASI88 names no\nparticular recording.\n",
