Fork of DOSBox SVN with its own DOS kernel. The machine setting picks the
|
|
emulated hardware: mda, cga and its composite variants, hercules,
|
|
hercules_plus, hercules_incolor, hercules_color, tandy, pcjr, amstrad,
|
|
olivetti/m24/att6300, pc3270, ega, ega200, jega, mcga, vgaonly, the S3,
|
|
Tseng, Paradise and ATI SVGA cards, the vesa variants, and pc98/pc9801/pc9821.
|
|
fm_towns is marked STUB in the same list.

No system BIOS: the PC BIOS, VGA BIOS, video fonts, keyboard layouts, codepage

Files named without a directory are searched in the working directory, the
|
|
program directory, the user configuration directory and the resource
|
|
directory. On Linux the configuration directory is $XDG_CONFIG_HOME/dosbox-x
|
|
or ~/.config/dosbox-x, and the resource directory is $APPDIR/usr/share/dosbox-x
|
|
inside an AppImage, otherwise $XDG_DATA_HOME/dosbox-x, then
|
|
/usr/local/share/dosbox-x, then /usr/share/dosbox-x. Windows uses C:\DOSBox-X.

Configuration: -conf and -userconf name the files to read. Otherwise
|
|
dosbox-x.conf then dosbox.conf is tried in the working directory, then in the
|
|
program directory, then in the configuration directory, which is last tried
|
|
for dosbox-x-<version>.conf; that file is written with the defaults when it
|
|
does not exist.

MT-32: libmt32emu is built from src/libs/mt32. Only four file names are ever
|
|
opened, and each candidate is identified by exact file size then SHA1, so the
|
|
name says nothing about the contents. addROMFile matches against the full
|
|
image list only, which rejects the interleaved chip dumps.

mt32.model = auto opens CM32L_CONTROL.ROM then MT32_CONTROL.ROM, and
|
|
CM32L_PCM.ROM then MT32_PCM.ROM; cm32l keeps only the CM32L names, mt32 only
|
|
the MT32 names. The directory is mt32.romdir, then the working directory, then
|
|
the resource directory, then the configuration directory. A missing pair logs
|
|
the accepted file names and disables the device.

FluidSynth reads fluid.soundfont; fluid_synth_sfload is the only check. With

the setting empty it probes /usr/share/soundfonts/default.sf2,
|

/usr/share/sounds/sf2/FluidR3_GM.sf2 and GeneralUser_GS.sf2 on Linux, and
|
|
C:\soundfonts\default.sf2 then the two same names under C:\DOSBox-X on Windows.

PC-98 character generator, tried in order: FONT.ROM as generated by T98Tools,
|
|
then the FONTX2 files named by pc-98 fontx sbcs and pc-98 fontx dbcs, then the
|
|
file named by pc-98 anex86 font or ANEX86.BMP followed by FREECG98.BMP, then
|
|
the built-in FREECG single-byte font and the built-in Japanese double-byte
|

font. Each stage fills only what the previous one left empty.

PC-98 sound board BIOS: with pc-98 sound bios set, SOUND.ROM is read from the

DOS/V and CJK text: fontxsbcs, fontxsbcs16, fontxsbcs24, fontxdbcs,
|

fontxdbcs14 and fontxdbcs24 name font files. LoadFontxFile reads a FONTX2
|
|
header, otherwise tries BDF and PCF, otherwise accepts a raw bitmap font
|
|
identified by its size, which covers ASC16 and ASCFONT.15 from UCDOS and ETen
|
|
Chinese DOS, ASC24, HZK14, HZK16, HZK24 and STDFONT.15 and STDFONT.24.

BOOT -bios loads a BIOS image at the top of the first megabyte, truncated to

128 KB, or 96 KB on PC-98 where it also looks for <image>.itf.rom, <image>.ITF.ROM,

BIOSTEST.COM loads an image of up to 64 KB at F000:0 and restarts the CPU at
