docs: update readme and database for ground truth feature

Add new emulator profiles (ares, BigPEmu, Eden, Model2, PrimeHack, Supermodel, Suyu, Xenia Canary, Yuzu) under emulators/*.yml with metadata, notes, file lists and exclusion/hle details. Update README counts (emulators/systems/files summary and auto-generated timestamp) and bump generated_at in database.json. Adjust mkdocs.yml navigation counts and add Yuzu entry to the Emulators nav.

+## Documentation site
+
+The [documentation site](https://abdess.github.io/retrobios/) provides:
+
+- **Per-platform pages** with file-by-file verification status and hashes
+- **Per-emulator profiles** with source code references for every file
+- **Per-system pages** showing which emulators and platforms cover each console
+- **Gap analysis** identifying missing files and undeclared core requirements
+- **Cross-reference** mapping files across 9 platforms and 328 emulators
+
+## How it works
+
+Documentation and metadata can drift from what emulators actually load.
+To keep packs accurate, each file is checked against the emulator's source code.
+
+1. **Read emulator source code** - trace every file the code loads, its expected hash and size
+2. **Cross-reference with platforms** - match against what each platform declares
+3. **Build packs** - include baseline files plus what each platform's cores need
+4. **Verify** - run platform-native checks and emulator-level validation

+  Amiberry is an Amiga emulator based on WinUAE, available as both standalone
+  and libretro core. No built-in kickstart — requires a real Kickstart ROM or
+  external AROS replacement files (aros-ext.bin + aros-rom.bin).
 
-  Core option "amiberry_kickstart" selects the ROM file:
-  auto, kick.rom, kick13.rom, kick20.rom, kick31.rom, kick205.rom,
-  kick40068.A1200, kick40068.A4000, cd32.rom, cdtv.rom.
-  "auto" selects based on the model option.
-  ref: BlitterStudio/amiberry/libretro/libretro.cpp:558,621-634
+  Libretro core option "amiberry_kickstart" overrides ROM selection: auto,
+  kick.rom, kick13.rom, kick20.rom, kick31.rom, kick205.rom, kick40068.A1200,
+  kick40068.A4000, cd32.rom, cdtv.rom. "auto" selects per model.
+  ref: libretro/libretro.cpp:558,621-640
 
-  Standalone mode ships with data/ directory (UI icons, virtual keyboards,
-  floppy sounds, AmigaTopaz.ttf font, gamecontrollerdb.txt). These are
-  compiled into the standalone binary but the libretro core may look for
-  them in the system directory.
+  Libretro ROM search directories (in order): save_dir/Kickstarts,
+  system_dir/Kickstarts, system_dir/save-data/Kickstarts, system_dir.
+  ref: libretro/libretro.cpp:2722-2742
+
+  Standalone ROM path: configurable via amiberry.conf "rom_path" setting.
+  Batocera sets this to /userdata/bios/amiga/. Fallback search order:
+  {home_dir}/roms/kick.rom, {home_dir}/kick.rom, ../shared/rom/kick.rom,
+  ../System/rom/kick.rom, then ROM database guess.
+  ref: src/memory.cpp:2030-2072
+
+  ROM identification uses SHA1 against WinUAE database (340+ entries) but does
+  not reject unknown ROMs. Cloanto encrypted ROMs supported with rom.key.
+  ref: src/rommgr.cpp:111-1100,1731-1787
+
+  Munt MT-32/CM-32L emulation compiled in (WITH_MIDIEMU). ROMs loaded from
+  mt32-roms/ subdirectory of the ROM path. Split ROM pairs supported
+  (e.g. pcm_mt32_l.rom + pcm_mt32_h.rom).
+  ref: src/midiemu.cpp:82-157
+
+  Keyboard MCU emulation (keyboard_mode setting) loads MCU ROMs via ROM
+  database scanning. Three MCU types supported: 6570-036 (A500/A600/A1000),
+  68HC05 (A1200), D8039HLC (A2000).
+  ref: src/kbmcu/keyboard_mcu_6500_1.cpp:385, keyboard_mcu_6805.cpp:544,
+  keyboard_mcu_d8039hlc.cpp:235
+
+  WHDLoad autoboot requires whdboot/ directory with boot-data.zip, WHDLoad,
+  AmiQuit, JST, whdload_db.xml. These ship with the standalone build but must
+  be obtained separately for the libretro core.

+  Multi-system emulator by Near (byuu), successor to higan/bsnes. Focuses on
+  accuracy and preservation. 38 systems emulated.
+
+  Firmware identification uses SHA256 hashes. Filenames are user-defined; ares
+  scans a configured directory and matches by hash. EmuDeck installs ares as
+  Flatpak (dev.ares.ares), configures biosPath in settings.bml.
+  ref: desktop-ui/settings/firmware.cpp:116-136
+
+  Firmware path resolution: settings.paths.firmware (user override) or
+  {userData}/ares/Firmware/ (default). Per-system firmware assigned in
+  Settings > Firmware dialog or via scan-by-hash.
+  ref: desktop-ui/settings/settings.hpp:90-102, desktop-ui/desktop-ui.cpp:68-75
+
+  Systems with fully embedded firmware (no user files needed):
+  Game Boy (boot.rom), Game Boy Color (boot.rom), Mega Drive (TMSS),
+  Sega 32X (TMSS + vector + SH2 boot M/S), Nintendo 64 (PIF NTSC/PAL/SM5 +
+  CIC 6101/6102/6105/7101), Super Famicom (IPL + all coprocessor firmware:

+  Neo Geo BIOS: accepts ZIP archive (neogeo.zip) or direct binary. AES looks

+  requires mie.zip with the 315-6146 MCU firmware.
+
+  Supported launch modes via -run= parameter:
+    dc, naomi, naomi2, hikaru, atomiswave, gaelco, cave3rd, segasp.
+
+  BIOS requirements verified against Batocera configgen, batocera-systems

+  Eden is a standalone Nintendo Switch emulator, community fork of yuzu by Camille LaVey.
+  dev.keys can be used instead of prod.keys when use_dev_keys is enabled (for Switch dev units).
+  Firmware (system NCAs) must be installed through Eden's UI from a firmware ZIP or NCA folder.
+  Required for commercial games. Homebrew (.nro, .nso) can run without keys or firmware.

 notes: |
   FS-UAE is an Amiga emulator by Frode Solheim, based on UAE/WinUAE.
 
-  ROMs loaded from save_dir/fsuae/Kickstarts/ (not system_dir).
-  base_dir = RETRO_ENVIRONMENT_GET_SAVE_DIRECTORY/fsuae (paths.c:197).
-  Also scans base_dir/AmigaForever/Amiga Files/Shared/rom/ (config.c:129-135).
-  Scans for .rom and .bin files. Identification by SHA-1 checksum, not filename.
-  AROS kickstart (512 KB) bundled in fs-uae.dat as fallback for all models.
-  rom.key enables decryption of Cloanto Amiga Forever encrypted ROMs.
+  Standalone: scans --kickstarts_dir for .rom/.bin files (default: Documents/FS-UAE/Kickstarts/).
+  Batocera overrides to bios/amiga/ via --kickstarts_dir (fsuaePaths.py:8, fsuaeGenerator.py:68).
+  Libretro port: scans save_dir/fsuae/Kickstarts/ (frozen at v2.7.15).
+  Identification by SHA-1 checksum, not filename (rommgr.cpp:92-151, romservice.py:78-91).
+  AROS kickstart (1 MB) compiled into binary as fallback for all models (rommgr.cpp:112).
+  rom.key searched in kickstart dir and multiple fallback paths (rommgr.cpp:1397-1498).
 
-  Supported models: A1000, A500, A500+, A600, A1200, A3000, A4000, CD32, CDTV.
-  Default model is A500 (config.c:42). Each model auto-selects its kickstart
-  via quickstart mechanism (cfgfile.c:7111-7154, config.c:140).
+  Supported models: A1000, A500, A500+, A600, A1200, A3000, A4000, A4000T, CD32, CDTV.
+  Default model is A500. Each model auto-selects its kickstart via quickstart
+  mechanism (cfgfile.cpp:9468-9517 for A500, cfgfile.cpp:9732-9791 for dispatch).
 
-  The .info declares firmware_count=0. All ROMs are auto-discovered by
-  directory scan, not by explicit filename lookup.
-
-  Libretro port is frozen at v2.7.15. Upstream ROM database is larger (3030
-  vs 1980 lines in rommgr). Core functionality equivalent for standard models.
+  ROM database shared between standalone and libretro (same WinUAE-derived rommgr.cpp).
+  Upstream v5.0.7 has a larger database (332 vs ~200 ROM IDs in libretro port).
+  Also supports Arcadia, ALG, freezer cartridges, SCSI/CPU board ROMs when configured.

+  for shared library resolution.
+
+  Each distribution ships a statically linked binary (pico8/vox) and a dynamically
+  linked variant (pico8_dyn/vox_dyn). Batocera uses the static binary. The .dat

+
+  PICO-8 supports x86_64 and ARM (Raspberry Pi). Voxatron x86_64 only.

+  Standalone MSX emulator supporting MSX1 through turboR, ColecoVision,
+  Spectravideo, and Pioneer LaserDisc hardware. Uses XML machine definitions
+  (share/machines/) that describe complete hardware configurations and
+  reference system ROMs by filename and SHA1 hash.
+
+  ROM resolution via FilePool (src/file/FilePool.cc, FilePoolCore.cc):
+  searches configured directories for files matching SHA1 checksums.
+  Filenames are secondary hints; SHA1 is the primary lookup key.
+  Files may be gzipped or individually zipped.
+
+  Batocera configgen (openmsxGenerator.py) configures filepool paths
+  (/userdata/bios/Machines position 1, /userdata/bios/openmsx position 2)
+  and selects machines per system type:
+    msx1, msx2 -> Boosted_MSX2_EN (enhanced Philips NMS 8245)
+    msx2+      -> Boosted_MSX2+_JP (enhanced Panasonic FS-A1WSX)

+    spectravideo -> Spectravideo_SVI-328
+    laserdisc (.ogv) -> Pioneer_PX-7
+
+  C-BIOS (open source MSX BIOS replacement) is shipped with openMSX in
+  Contrib/cbios/ and supports cartridge-only games. Not used by Batocera.
+
+  237 machine definitions exist in total. Each machine has its own ROM
+  requirements. Only ROMs for Batocera-selected machines are listed here.
+  Users selecting other machines via openMSX GUI need additional ROMs.

+
+notes: |
+  shadPS4 is a standalone PlayStation 4 emulator. Most PS4 system libraries
+  are reimplemented in HLE. For better game compatibility, real firmware
+  modules (.sprx) can be loaded in LLE mode from the sys_modules/ directory.
+
+  Modules are loaded by sysmodule_internal.cpp via loadModuleInternal().
+  If a module exists in sys_modules/, it is loaded as LLE. If absent and
+  an HLE implementation exists, the emulator falls back to HLE. If neither,
+  the module is stubbed and games needing it may fail.
+
+  Game-specific overrides are supported: sys_modules/{CUSA_ID}/ takes
+  priority over the global sys_modules/ directory.
+
+  System fonts are mounted from fonts/font/ (/preinst/common/font on real
+  PS4) and fonts/font2/ (/system/common/font2 on real PS4). These are SST
+  (Sony Standard Text) typeface files in OTF format. The emulator mounts
+  the directories wholesale; games load individual fonts by name. Without
+  fonts, the emulator warns "No dumped system fonts, expect missing text
+  or instability."
+
+  All firmware files are extracted from a real PS4 via FTP:
+  - .sprx modules from /system/common/lib/
+  - font/ from /preinst/common/font/
+  - font2/ from /system/common/font2/
+
+  Batocera configgen (shadps4Generator.py) configures display, input, and
+  saves but does not map BIOS/firmware paths. The emulator uses its own
+  user directory for sys_modules/ and fonts/.

+  Open-source Sega Model 3 arcade emulator by Bart Trzynadlowski (trzy) and
+  contributors, under GPL-3.0. Emulates all three Model 3 steppings (1.0, 1.5,
+  2.0/2.1) including Real3D graphics, SCSP sound, DSB1/DSB2 MPEG music boards,
+  drive boards, and net board. Cross-platform (Windows, Linux, macOS).
+
+  Uses MAME-compatible ROM sets loaded from ZIP archives. GameLoader identifies
+  games by CRC32 checksums defined in Config/Games.xml. Parent/child ROM set
+  relationships exist between regional variants of the same game, not as shared
+  BIOS sets. No standalone BIOS or firmware files are loaded outside of game ZIPs.
+
+  EmuDeck installs the Flatpak package (com.supermodel3.Supermodel). Config
+  stored in ~/.supermodel/Config/. No checkBIOS entry in EmuDeck.

+  The Sega Model 3 arcade hardware has no shared system BIOS. Each game board
+  contains its own program ROMs (CROM), video ROMs (VROM), sound program, sound
+  samples, and optional DSB/drive board ROMs, all contained within per-game
+  MAME-format ZIP archives. Supermodel loads all required data from these game
+  ZIPs via CRC32-based identification defined in Games.xml. No standalone BIOS
+  or firmware files are referenced by the emulator source code.

 notes: |
-  VBA-Next is a Game Boy Advance emulator forked from VBA-M, optimized for
-  libretro. It includes a built-in HLE BIOS (myROM array in src/gba.cpp:8423)
-  that handles all standard SWI calls, so no external BIOS file is needed for
-  most games.
+  Frozen snapshot of VBA-M circa 2011, optimized for libretro by Squarepusher.
 
-  BIOS loading is gated behind HAVE_HLE_BIOS (defined in build/Makefile.common)
-  and controlled by core option vbanext_bios (default: enabled). When enabled,
-  the libretro port looks for gba_bios.bin in RetroArch's system directory
-  (libretro/libretro.cpp:198-203). CPUInit() loads the file via utilLoad(),
-  validates it is exactly 0x4000 bytes (16 KB), and sets useBios = true
-  (src/gba.cpp:12413-12443). If loading fails or the option is off, the HLE
-  BIOS (myROM) is memcpy'd into the bios buffer instead.
+  Built-in HLE BIOS (myROM array, src/gba.cpp:8423) handles all standard SWI
+  calls. No external BIOS file needed for most games.
 
-  CPUIsGBABios() accepts extensions: .gba, .agb, .bin, .bios, .rom
+  BIOS loading gated by HAVE_HLE_BIOS (build/Makefile.common:3) and core option
+  vbanext_bios (default: enabled). When enabled, retro_init resolves gba_bios.bin
+  in system_dir (libretro/libretro.cpp:198-202). CPUInit loads via utilLoad(),
+  validates size == 0x4000, sets useBios = true (src/gba.cpp:12430-12438). On
+  failure, myROM is memcpy'd as HLE fallback (src/gba.cpp:12443).
+
+  With real BIOS, execution starts at 0x00000000 (BIOS entry point). Without,
+  jumps to 0x08000000 (ROM entry), skipping boot animation
+  (src/gba.cpp:12657-12675).
+
+  CPUIsGBABios accepts extensions: .gba, .agb, .bin, .bios, .rom
   (src/gba.cpp:8851-8873).
 
-  When useBios is true and skipBios is false, execution starts at 0x00000000
-  (real BIOS entry). Otherwise it jumps straight to 0x08000000 (ROM entry),
-  skipping the boot animation (src/gba.cpp:12657-12675).
-
-  The HLE BIOS covers: SoftReset, RegisterRamReset, Halt, VBlankIntrWait,
-  Div, Sqrt, ArcTan, ArcTan2, CpuSet, CpuFastSet, GetBiosChecksum,
-  BgAffineSet, ObjAffineSet, BitUnPack, LZ77UnComp (WRAM/VRAM),

-  Diff16bitUnFilter, MidiKey2Freq, SndDriverJmpTableCopy
-  (src/gba.cpp:2369-2578).
-
-  Some per-game overrides in gbaover[] (libretro/libretro.cpp:235) have a
-  useBios field, but all entries currently set it to 0 (no game forces BIOS).
+  Upstream VBA-M CPUInit (src/core/gba/gba.cpp:3674-3702) is functionally
+  identical. No divergences in BIOS handling.

-  VeMUlator is a Sega Dreamcast Visual Memory Unit (VMU/VMS) emulator ported
-  from Android (Java) to C++ for libretro. It emulates the Sanyo LC8670
-  "Potato" CPU, 128 KB flash memory, 48x32 monochrome LCD, piezo buzzer,
-  and basic timer subsystems.
+  Sega Dreamcast VMU/VMS emulator. Same author (Mahmoud Jaoune) ported
+  the original Android Java app to C++ for libretro. Emulates the Sanyo
+  LC8670 CPU, 128 KB flash, 48x32 LCD, piezo buzzer, and timers.
 
-  No BIOS files are required. The core uses High Level Emulation (HLE) to
-  bypass the VMU firmware entirely:
+  No BIOS files required. The core uses HLE exclusively: startCPU()
+  checks BIOSExists (always false), then initializeHLE() sets SFR
+  registers and system RAM directly (vmu.cpp:193-222).
 
-  - At startup, startCPU() checks the BIOSExists flag (vmu.cpp:195). When
-    false (always, in the libretro port), it calls initializeHLE() which
-    sets up SFR registers (SP=0x7F, PSW=0x02, IE=0x80, MCR=0x08, P7=0x02,
-    OCR=0xA3, BTCR=0x41) and system RAM variables directly (vmu.cpp:206-222).
-
-  - A loadBIOS() function exists in the VMU class (vmu.cpp:82-137) and can
-    handle both encrypted (XOR 0x37, 4-byte header stripped) and unencrypted
-    BIOS images (first byte must be 0x2A = JMPF opcode). Maximum accepted
-    size is 0xF004 (61444) bytes, loaded into 0xF000 (61440) bytes of ROM.
-    However, this function is never called by the libretro frontend code.
-    retro_load_game() in main.cpp only loads game flash data, with no BIOS
-    path resolution or RETRO_ENVIRONMENT_GET_SYSTEM_DIRECTORY call.
-
-  - The README lists "BIOS support" as a planned future feature.
-
-  The .info file declares no firmware entries (firmware_count absent).
-  Supported ROM formats: VMS (.vms), DCI (.dci), raw flash dump (.bin).
-  The core option "enable_flash_write" allows persistent saves for .bin files.
+  A loadBIOS() function exists (vmu.cpp:82-137) handling encrypted and
+  unencrypted BIOS images, but is never called from the libretro
