Profiles that read two repositories, a libretro port and its upstream, now prefix each citation with source or upstream, decided by which tree carries the cited value at its pin. The emulator pages use the word to tell libretro glue, emulator code as the port carries it, and the upstream emulator apart.

notes: |
|
|
Qt front end that installs and drives its own RetroArch and its own fork of
|
|
ParaLLEl N64. RetroArch is fetched from buildbot.libretro.com as a stable
|
|
release archive (src/updaters/retroarch-updater.cpp:24-30). The core,
|
|
parallel_n64_next_libretro, is fetched from parallel-launcher.ca
|
|
(src/core/updates.cpp:190-213) into retro-data/cores. Core version at this profiling
|
|
is 2.28.
|
|
|
|
Neither lands in a user RetroArch install. The system directory the core
|
|
reads from is retro-data/system under the launcher's own data directory,
|
|
written into a private retroarch.cfg on every launch (src/core/retroarch.cpp:100-129).
|
|
RetroArch is spawned as `-L <core> --config <cfg> <rom>`
|
|
(src/core/retroarch.cpp:760-781). The launcher also rewrites the core's .info into
|
|
retro-data/info at every startup (src/main.cpp:149-156), which is how RetroArch
|
|
learns of the 64DD firmware entry.
|
|
|
|
Content is restricted to cartridge formats at every entry point: command line
|
|
and file associations take .z64 .n64 .v64 .bps (src/main.cpp:65-94), the add-ROM
|
|
dialog the same (src/ui/main-window.cpp:607-616), the library scanner *.[nvz]64
|
|
(src/core/rom-finder.cpp:271-278), romhacking.com downloads .z64 (src/rhdc/core/sync.cpp:238). A .bps
|
|
is patched to a cartridge ROM before launch (src/ui/play.cpp:721-757). No --subsystem
|
|
argument is passed either, so neither route into the core's disk path opens:
|
|
the header check at libretro/libretro.c:545-548 and the cart-and-disk subsystem at
|
|
libretro/libretro.c:104-114.
|
|
|
|
Graphics plugin is chosen per ROM among ParaLLEl-RDP, Glide64, angrylion,
|
|
GLideN64, Rice, glN64 and OGRE (src/core/settings.hpp:13-22, src/core/retroarch.cpp:55-64).
|
|
|
|
Selecting glN64 also reads gles2n64.conf from the system directory root at
|
|
plugin init, and writes it out with defaults when it is absent
|
|
(gles2n64/src/glN64Config.c:246-254, Config_WriteConfig at gles2n64/src/glN64Config.c:95).
|
|
|
|
Three paths the fork computes but never reads. GLideN64 builds without
|
|
FreeType here, so the font file name it resolves for on-screen text is
|
|
assigned and dropped (mupen64plus-video-gliden64/src/TextDrawer.cpp:145-188). Its per-game ini is compiled in
|
|
as a header and the external copy is skipped because the launcher writes INI
|
|
Behaviour as disabled on every launch (src/core/retroarch.cpp:468,
|
|
mupen64plus-video-gliden64/src/mupenplus/Config_mupenplus.cpp:170-241, libretro/libretro.c:2030-2040). Rice's ini reader and
|
|
writer sit behind #if 0 (gles2rice/src/RiceConfig.cpp:453-463, gles2rice/src/Video.cpp:327-333).

note: "Read from the system directory root when disk content is loaded, with no size or hash check. The core drops into its dead-emulator loop when it is absent. Content counts as disk when its header carries a 64DD magic word, or when it arrives on the second slot of the cart-and-disk subsystem."
