np2pi reads 0x4000 bytes of scsi.rom as the SCSI BIOS (cbus/scsiio.c: 208-233). The only 16 KB copy of that name is Clock Signal's Apple II card ROM, which the name step served and the RetroPie manifest installed. The entry now carries unsourceable: and np2pi falls back on its stub.

Raspberry Pi build by eagle0wl of Yui's Neko Project II 0.83
|
|
(np2ver.h:1), the SDL front end compiled with sdl/makefile.rpi and
|
|
sdl/raspberrypi/compiler.h. That header defines SUPPORT_SASI and
|
|
SUPPORT_SCSI but not SUPPORT_PC9821, and bios/bios.c defines
|
|
BIOS_SIMULATE, so bios9821.rom and itf.rom are never opened: the ITF
|
|
image is the itfrom.res table compiled into the binary.
|
|

|
|
|
|
Every file below is opened from the working directory. datadir is "./",
|
|
file_setcd(datadir) makes it the base of file_getcd, and getbiospath
|
|
falls back to file_getcd while the biospath key of np2.cfg is empty, as
|
|
it is by default. np2.cfg itself is read and written there.

RetroPie launches np2 from its pc98 configuration directory, where it
|
|
links 2608_bd.wav, 2608_hh.wav, 2608_rim.wav, 2608_sd.wav,
|
|
2608_tom.wav, 2608_top.wav, bios.rom, FONT.ROM and sound.rom from the
|
|
pc98 folder of its BIOS directory, and TakaoGothic as default.ttf. The
|
|
paths below follow that folder. The other files are read only when
|
|
placed in the working directory itself.
|
|
|
|
Fonts are filled in order and each source only supplies the glyphs still
|
|
missing: the fontfile key of np2.cfg (empty by default), FONT.BMP,
|
|
FONT.ROM, then the PC-8801 KANJI1.ROM, KANJI2.ROM and PC88.FNT. Glyphs
|
|
still missing after that are drawn from default.ttf through SDL_ttf into
|
|
font.tmp, which is reused on later runs. default.ttf is a desktop font,
|
|
not a machine ROM.
