feat: profile QUASI88kai standalone
The ROM list is src/memory.cpp:87-100. A missing ROM is filled with 0xFF and the emulator starts, so only N88.ROM, N88SUB.ROM and N88EXT0.ROM, without which nothing boots, are required. The directory is QUASI88_ROM_DIR, else <home>/rom (src/file-op.cpp:444-521). The CMake ROMDIR setting only appears in the help text.

notes: |
|
||||
Continuation of Showzoh Fukunaga's QUASI88, version 0.7.1 at the pinned
|
||||
commit (CMakeLists.txt:3). It reads every ROM, the OPNA rhythm samples and
|
||||
the floppy drive sound samples from one ROM directory.
|
||||
|
||||
The ROM directory is $QUASI88_ROM_DIR when set, else the rom folder under the
|
||||
QUASI88 home (src/file-op.cpp:444-464,521). The home is the working
|
||||
directory when it holds quasi88.ini, else $HOME/.quasi88 (src/file-op.cpp:
|
||||
494-516). The -romdir option replaces it (src/getconf.cpp:282-290,529). The
|
||||
CMake ROMDIR setting becomes the ROM_DIR macro (CMakeLists.txt:31,38), which
|
||||
only fills the help text (src/help.h:214) and does not move the search.
|
||||
Paths below are relative to the QUASI88 home.
|
||||
|
||||
load_rom tries each name of an entry in order inside the ROM directory and
|
||||
stops at the first that opens (src/memory.cpp:175-219). A missing ROM is
|
||||
filled with 0xFF, and a short one is padded with 0xFF, so the emulator starts
|
||||
with any ROM missing. The machine model comes from byte 0x79D7 of N88.ROM
|
||||
(src/memory.h:44, src/memory.cpp:503), and BASIC_AUTO, the default, boots V2
|
||||
when that byte is "4" or higher and V1S otherwise (src/initval.h:53,
|
||||
src/pc88main.cpp:2755-2761).
|
||||
|
||||
-compatrom FILE loads every main and sub ROM from one P88SR.EXE image
|
||||
instead of the separate files (src/getconf.cpp:535, src/memory.cpp:341-369).
|
||||
There is no default name.
|
||||
|
||||
With -samples (off by default, src/snddrv/quasi88/mame-quasi88.cpp:506-510,
|
||||
src/snddrv/quasi88/SDL/audio.cpp:91-94) the drive sounds motoron.wav,
|
||||
motoroff.wav, headdown.wav, headup.wav and seek.wav are read from the ROM
|
||||
directory (src/snddrv/quasi88/mame-quasi88.cpp:101-108,1085-1127). Any mono
|
||||
WAV is accepted (src/snddrv/quasi88/mame-quasi88.cpp:92). QUASI88 names no
|
||||
particular recording.
