The pin sat on master, the Dojo 6 line, while the releases are tagged on the dojo branch (flyinghead f13d7ad plus the Dojo commits). At dojo-7.8 (745815c): UseReios defaults to on, the boot ROM and flash logic lives in hw/flashrom/nvmem.cpp, dc_nvmem.bin.net and the netplay reios override are gone, font.bin is a compiled-in resource, BIOS ROMs are matched by CRC32 then name, airlbios.zip is read by the two Airline Pilots sets, and System SP (segasp.zip) is a platform. naomi.zip and naomi2.zip gain the g, b, Korea and multi-region members.

|
Fork of Flycast adding rollback and delay netplay, a lobby, spectating,
|
|
replay recording and a training mode. The Dojo 7 releases are tagged on the
|
|
dojo branch, which carries flyinghead/flycast up to f13d7ad of 2024-05-11
|
|
with the Dojo commits on top. The master branch is the older Dojo 6 line.
|
|
The build names itself with git describe, so the version string is the tag.
|
|
ref: .github/workflows/build-and-release.yml:4-6, .github/workflows/build-and-release.yml:27
|
|
|
|
Every file below is read from the data directory, flat, with no subfolder.
|
|
The user data directory is <exe>/data on Windows,
|
|
$XDG_DATA_HOME/flycast-dojo or $HOME/.local/share/flycast-dojo on Linux,
|
|
the data/ folder of $HOME/.flycast or ~/Library/Application Support/Flycast
|
|
on macOS, and /flycast-dojo/data on Switch. A missing file is then looked up
|
|
in the system data directories (on Linux $XDG_DATA_DIRS or /usr/local/share
|
|
and /usr/share, each with flycast-dojo appended, every $FLYCAST_BIOS_PATH
|
|
entry, ./ and data/), then in the directory of the loaded game. Boot ROMs,
|
|
flash and arcade BIOS archives are also searched in every ContentPath entry.
|
|
ref: core/linux-dist/main.cpp:148-178, 255-296, 337-344,
|
|
core/windows/winmain.cpp:77-97,
|
|
shell/apple/emulator-osx/emulator-osx/osx-main.mm:108-137,
|
|
core/stdclass.cpp:83-105, core/oslib/oslib.cpp:52-81, 88-103
|
|
|
|
The boot ROM prefix follows the platform (core/hw/flashrom/nvmem.cpp:35-50):
|
|
Dreamcast -> dc_
|
|
NAOMI -> naomi_
|
|
NAOMI 2 -> naomi2_
|
|
Atomiswave -> aw_
|
|
System SP -> no prefix
|
|
Boot ROM search pattern (core/hw/flashrom/nvmem.cpp:256-272):
|
|
{prefix}boot.bin, {prefix}boot.bin.bin, {prefix}bios.bin, {prefix}bios.bin.bin
|
|
Flash search takes a single name, {prefix}nvmem.bin, on Dreamcast only. The
|
|
arcade platforms keep their flash under the per-game save path, and when it
|
|
is absent the NAOMI and Atomiswave defaults compiled into the binary are
|
|
used for the games that have one (core/hw/flashrom/nvmem.cpp:214-254).
|
|
The aw_ prefix never reaches a filename: the boot ROM search is skipped on
|
|
Atomiswave, whose BIOS comes from awbios.zip.
|
|
|
|
Arcade BIOS archives are opened as <name>.zip, then <name>.7z
|
|
(core/hw/naomi/naomi_cart.cpp:57-75). Each ROM is looked up by CRC32 in
|
|
the game archive, its parent and the BIOS archive, then by file name in
|
|
the same order, and the blob of the configured region is taken, else the
|
|
first one listed. awbios declares no CRC32, so its member is found by name.
|
|
No hash is checked on an archive. A game with no bios field reads naomi.zip
|
|
and runs from the flat naomi_boot.bin when the archive is missing. A game
|
|
that names a BIOS aborts without it (core/hw/naomi/naomi_cart.cpp:190-206).
|
|
|
|
NAOMI 2 and System SP are platforms of their own: naomi_cart_GetPlatform
|
|
returns DC_PLATFORM_NAOMI2 for a game whose bios field is naomi2 and
|
|
DC_PLATFORM_SYSTEMSP for segasp (core/hw/naomi/naomi_cart.cpp:785-806).
|
|
|
|
UseReios defaults to on, so the Dreamcast boots through reios and reads
|
|
dc_boot.bin only when HLE BIOS is turned off, to start the BIOS menu
|
|
without a disc, or for the product ids that force the real BIOS
|
|
(core/cfg/option.cpp:127, core/emulator.cpp:262-279, 502-526).
|
|
|
|
The release archives hold the binary and its libraries alone. The default
|
|
arcade flash images, the on-screen button sheet and the reios font are
|
|
compiled in as resources.
|
|
ref: CMakeLists.txt:966-1001, .github/workflows/build-and-release.yml:56,
|
|
.github/workflows/build-and-release.yml:71-72
|
|
|
|
Also read but never user supplied: buttons.png overrides the compiled in
|
|
button sheet (core/rend/osd.cpp:155-174), mappings/*.cfg are written by the
|
|
input configuration screen (core/input/mapping.cpp:401, 461-463),
|
|
flycast.lua is a user script (core/lua/lua.cpp:750-760), and the training
|
|
mode runs training/cvs2.lua or training/mvsc2.lua from the config directory
|
|
for those two games, otherwise training/<game>.lua from the data directory
|
|
(core/dojo/dojo.cpp:287-319).
