Port changes are VR, DSU and audio options, no file loading. The
SegaBoot refs now cite the libretro lookup (Sys, then User/Triforce)
at AMMediaboard.cpp:500-514; upstream to e1d35f6, CommonPaths.h same.
bennugd, eden, play, scummvm and uzem cited files their repositories have
since moved (libretro.c into libretro/, fs_paths.h into src/common/fs/,
uzem.cpp into oldsrcs/). Lines unchanged. scummvm's upstream_commit is
its fork base e0ddc60.
The note citations hold under three source pins; read again at 583f0e9 they land on the acgame loader, the BIOS scan and the resource reads, recorded as prose_written_at. GameDatabase.cpp:39, Patch.cpp:117, SDLInputSource.cpp:24 and linux_build_qt.yml:129 read the same in the fork, the tree RetroBat ships.
libretro/Omicron master is msx80/Omicron aaaa2f1 (2020-09-29) plus .gitlab-ci.yml and the core Makefile. Upstream HEAD 49e4e05 is 168 commits later and moved the libretro frontend files the notes cite.
upstream_commit 3353efd3 is the higan v106r25 release commit nSide synced with (Emulator::Version 106.25). gitlab higan HEAD 00684d2 is a later higan and stays out.
Boot.cpp:408-442, WiimoteEmu.cpp:156-165, NWC24Config.cpp:17 and TitleDatabase.cpp:54-58 land on their code in Dolphin-MMJR2 at 4d0fdb8 and miss it in dolphin-emu at 4ff214c: every citation reads the fork.
Profile the rommgr.cpp table at 376b22c: 208 entries for CPU boards,
freezer cartridges, SCSI and IDE controllers, Picasso IV, x86
bridgeboards, CD32 FMV and the CD32/CDTV images the scan identifies
by SHA-1. A CPU board without its ROM does not start, so the A1200
and A4000 accelerator quickstarts need these files.
The bulk advance moved upstream_commit to upstream HEAD. On freej2me_plus,
hakux, kronos, mesen-s, np2kai and snes9x it was, and still is, the
merge base of upstream with the fork's pin (GitHub compare), the revision
the port carries. ax360e, nes-emu and snes9x-explus vendor an upstream
tree whose commit their notes name.
The zn.c rewrite filed the Time Warner and Raizing BIOS sets under new
ids zn1-atari and zn1-raizing, which have no name and stop
generate_site. Every other MAME profile files them as atari-zn1 and
eighting-zn1 (Raizing is Eighting's label).
The 2.43 tag sits on main2 (b5ae1af, changelog ending at 1.38) while
the 2.43.apk asset carries main4's changelog and RPCS3 20071-1f080485.
The two branches share merge base d4622157. The pin c6ca182 already
names the released tree.
Music tracks are now looked up through the audio language chain,
music/<language>/ first and then music/, and a catalog row may list
alternate names (backend_files.c:108-134). Same level, FMV and track
names.
Upstream split the sound code into crates (soundblaster, sc55, mt32,
gus). The AWE32 and Sound Canvas tables are unchanged. Adds the
optional 128 KB Verite board ROM that verite_rom names, which the
emulated RISC reads in place of the image the emulator builds
(src/bus/verite.rs:45-71).
Upstream changes at the cited lines are the sprite atlas type passed to
loadSff and a branch input for the screenpack clone in the release
workflow. Every file is still read from the same place.
rom_load now maps Scorpion ZS-256, ZS-256 Turbo+, Scorpion GMX and
Didaktik Gama to four new bundled ROMs (src/cpu.c:3549-3564), sized by
get_rom_size at 64K, 64K, 512K and the 16K default. The TK90X Ferranti
models reuse tk90x.rom and tk90xs.rom. Both ZX Evolution ROM images
were replaced upstream, so their sha1 changed.
The game database now merges resources/emucorex_overrides.yaml over
GameIndex.yaml (GameDatabase.cpp:1274-1278), and a libvulkan_malisx2.so
driver is kept only on the Mali GPUs GpuDriverCompatibility.kt:204-208
lists. tfx.glsl changed upstream. Both convert.glsl entries now carry
the size and sha1 of the vendored tree.
Build scripts now fetch PinMAME 652249e2; its cited lines only shifted. Music accepts an absolute script path, and PUP packs gain a PUPSOUNDS/ sound bank.
Adds the Memory Expansion Card ROM, the //c keyboard photo and the Monitor II and drive artwork, updates the //e keyboard photo, and follows the Virtual ][ list into VirtualIISoundCatalog.h with the Import sounds folder.
The converter now reads Plus.j2d of a JJ2+ install for the textured layers a level names, listed as an optional Source file. A Content tree holding Prebaked.pak skips the conversion, and a user Content directory beside Cache is searched first for content, music and translations. The rest of the loaders moved without a change in what they open.
hf.mpq now has its own CMake option, BUILD_MOD_MPQS, beside BUILD_ASSETS_MPQ. The loaders moved by two lines after a romfs search path was added for 3DS and Switch. Same files.
Upstream rebuilt the mediaclientaudio and scdv patch DLLs and added an epoc6 export to mediaclientaudio.dll.map. Two compatibility scripts were added, pottery_startup_fix.lua and wave_crash_fix.lua, and the first requires eka2l1.mem, now listed. The libretro fork only changed its link options. Refs into libmanager.cpp, graphics_ogl.cpp, screen.cpp and fbs.cpp are read on the standalone tree.
Firmware search and checks unchanged, the libretro code moved by seven lines. kAdamFirmwareMetadata no longer carries a SHA-1 per role, so the two sha1 fields go: the code knows size and CRC32 only.
Upstream replaced zn.c with the current MAME layout. The BIOS sets are now named after the board BIOS (coh1000c, coh3002c, coh1000t, coh1002m, coh1002v, coh1000a, coh1001l, coh1000w, coh1002e) and each carries its CAT702 key. Atlus, Time Warner and Raizing sets are dumped. New namcoc76.zip (Namco System 11 C76) and optional model1io.zip and model1io2.zip (Model 2 I/O boards). hiscore.dat changed, dotron.zip artwork added.
The pin already carried Cargo.toml version 0.13.2; HEAD only touches CI and the changelog. Prose citations now name load() at gb.rs:1377, load_boot_static at 1414 and load_boot_file at 1427.
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.
Pin d409fe7, the commit of the v0.3a-20261022-git-d409fe7 Supermodel
Dojo release, built from the dojo branch. The branch merges trzy at
98fcbff, which adds Real3D Pro-1000 emulation: pro1000.zip (cpu_rom,
init_rom) and the optional Assets/3dlogo.cmem and .pmem. Games.xml now
holds 64 sets. The launcher in Frontend/ is replaced by an in-emulator
GUI, and ROMs/ and Replays/ are path types on every platform.
v1.8.0 (4e899aa) searches the system directory, then the directory of
the loaded game, each for the loose BIOS and then stvbios.zip
(ss.cpp:1540-1582). Same files, sizes and hashes.
The pin 53f53e0 is the 1.0.9 tag commit, and the build names itself
from git describe (Common/Version.cpp). 1.0.9 ships a single Windows
zip whose Sys/ fonts and codehandler.bin match the declared hashes.
The 20251112 APKs are built from tag commit 9198dc2. HEAD 302b0c3 is a
sibling commit off the same base that only adds shader caches under
cache/, so src/ and every ref are identical at both.
The pin b2ff53f is release 2.5-4 (tag 65f1d85) plus a README commit, versionName 2.5 in app/build.gradle. Bare Java file names in the notes now carry their app/src/main/java path. No file changed.
The port now merges PCSX2 ab0b401f and embeds patches.zip, packed from the pcsx2_patches submodule (pcsx2/CMakeLists.txt:1183-1205, pcsx2/Patch.cpp:292-331). The resources copy is read only with PCEE2_EXTERNAL_RESOURCES set. Same files.
Disk images now open through the frontend VFS (Libretro/libretro.c:149-162, src/disk.c:13-65). No system file. core_version is the pin's commit date, the source carries only the git rev.
Same four files. A CD BIOS outside the two CRC32 constants is accepted on a plausible run address (libretro.c:5706-5781), and a custom cart boot ROM must be exactly 131072 bytes (libretro.c:6010-6050). core_version follows CORE_BASE_VERSION in the Makefile.
