fix: restore large files in release job

release job built packs without PS3UPDAT.PUP, PSVUPDAT.PUP, etc. producing tiny non-functional ZIPs (2-14 MB instead of 200+ MB).

-```bash
-# Full platform pack
-python scripts/generate_pack.py --platform retroarch --output-dir dist/
-python scripts/generate_pack.py --platform batocera --output-dir dist/
-
-# Single emulator or system

-python scripts/verify.py --platform batocera
-python scripts/verify.py --emulator flycast
-```
-
-Only dependency: Python 3 + `pyyaml`.
-
-## 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 319 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
+Full file listings, platform coverage, emulator profiles, and gap analysis: **[https://abdess.github.io/retrobios/](https://abdess.github.io/retrobios/)**

-  {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

-  Closed-source Windows emulator for Sega Dreamcast and related arcade hardware.
-  Run via Wine (32-bit, win32 prefix) on Linux platforms (Batocera, RetroBat).
-  Uses MAME ROM naming conventions for arcade BIOS archives.
-
-  Batocera configgen (demulGenerator.py) maps roms0 to the BIOS directory.
-  All BIOS ZIPs are placed directly in bios/ (no subdirectory prefix).
-  Demul searches configured ROM paths for both game ROMs and BIOS archives.
-
-  Gaelco PowerVR and Cave CV1000 (3rd gen) games are self-contained ROM sets
-  and do not require separate BIOS archives.
-
-  HLE MIE emulation available (changelog: "full HLE MIE" mode). LLE mode
-  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
-  declarations, MAME ROM set conventions, and community documentation.
-  No source code available for direct verification.

-# Storage defaults to data/ relative to executable.

-#   - RPKG files → extracted to drives/z/{firmcode}/ (system partition)
-#   - VPL firmware packages → extracted to roms/ and drives/
-#
-# drives/z/{firmcode}/ content is generated during installation, not

-notes: |
-  Pure standalone Symbian OS / N-Gage emulator. No libretro core.
-  Requires phone ROM dumps (SYM.ROM) obtained from real Nokia devices.
-  The emulator supports 100+ Nokia phone models (NEM-4, RH-29, RM-409, etc.).
-  No hash or size validation on the ROM file; the loader parses the ROM structure.
-  Batocera maps the ngage system to eka2l1 in configgen-defaults.yml.
-  No dedicated Batocera configgen generator exists.

 notes: |
  FS-UAE is an Amiga emulator by Frode Solheim, based on UAE/WinUAE.

-  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).
+  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.

-  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).
+  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).

-  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.
+  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.

-  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)
-    msxturbor  -> Boosted_MSXturboR_with_IDE (enhanced Panasonic FS-A1GT)
-    colecovision -> ColecoVision_SGM
-    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/.

-  Shared font, Mii data, country list and bad word list are embedded in
-  the binary via CMRC and compiled-in headers. DSP firmware is loaded from
-  the game ROM at runtime, not from an external file.
-  DSP modes: HLE (default), LLE (Teakra), Null.
-  Files are resolved from the RetroArch save directory
-  (<save_dir>/Emulator Files/sysdata/), not the system directory.

+  Quake engine source port. Plays Quake (id1), mission packs Scourge of Armagon
+  (hipnotic) and Dissolution of Eternity (rogue), Quoth mod, and custom mods via
+  -game parameter. The core accepts .pak extensions (retro_get_system_info sets
+  valid_extensions = "pak"). Content is loaded directly from the PAK file path -
+  the directory containing the PAK becomes basedir (libretro.c:988,1050).
+  The engine auto-detects game variant by checking the content path for id1,
+  hipnotic, rogue, or quoth substrings (libretro.c:1030-1070) and passes the
+  corresponding command-line flag. For non-standard paths it uses -game with the
+  directory basename. PAK files are game data (maps, textures, models, sounds)
+  shipped with the original retail game, not engine firmware. The engine checks
+  for gfx/pop.lmp inside pak0.pak to distinguish registered vs shareware
+  (common.c:974-991). COM_AddGameDirectory (common.c:1709) loads pak0.pak through
+  pak9.pak sequentially from the game directory, trying both lowercase and
+  uppercase filenames. No engine data files are required in the RetroArch system
+  directory. The core needs no BIOS or firmware.

-  ARM-optimized Amiga emulator by TomB, ported to libretro by Chips-fr.
-  Based on an older uae4arm version, intended for low-powered ARM hardware
-  where PUAE cannot maintain full speed.
-
-  Core options expose three models: A500, A600, A1200. Each selects its
-  Kickstart ROM automatically. Extended ROMs (CDTV/CD32) can be set via
-  .uae config files but CD32/CDTV hardware emulation is absent from
-  this port (no akiko chip, CD support listed as missing).
-
-  Built-in AROS Kickstart replacement used as fallback when no ROM is found.
-
-  Cloanto-encrypted ROMs require rom.key in the system directory.

-  Universal Machine Emulator — combined MAME + MESS before the official

-  with -DWANT_UME including both mame.mak and mess.mak. 69 arcade BIOS
-  root sets (identical to mame2015), plus 619 MESS computer/console
-  drivers. Source version.c says 0.159, .info claims 0.160.
-
-  Paths under system_dir/ume2015/ (samples, artwork, cheat, hash, ini).
-  Software list hash XMLs in system_dir/ume2015/hash/ (375 files from
-  repo hash/ directory, required for MESS software list support).
-  Per-game XML cheats in system_dir/ume2015/cheat/.
-  hiscore.dat loaded via f.open("hiscore", ".dat") without explicit
-  search path (libretro-specific path code disabled via #if 0).

-  Frozen snapshot of VBA-M circa 2011, optimized for libretro by Squarepusher.
+  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.

-  Built-in HLE BIOS (myROM array, src/gba.cpp:8423) handles all standard SWI
-  calls. No external BIOS file needed for most games.
+  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.

-  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

-  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).

-  Upstream VBA-M CPUInit (src/core/gba/gba.cpp:3674-3702) is functionally
-  identical. No divergences in BIOS handling.
+  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).

-  No BIOS files required. The core uses HLE exclusively: startCPU()

-  registers and system RAM directly (vmu.cpp:193-222).
+  No BIOS files are required. The core uses High Level Emulation (HLE) to

-  unencrypted BIOS images, but is never called from the libretro
-  interface. retro_load_game() only loads game flash data, with no
-  system directory query. README lists BIOS support as planned.
+  - 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.

-  The .info declares firmware_count=0 which is incorrect. No JiffyDOS support.

-  XRoar by Ciaran Anscomb emulates Dragon 32/64, Tandy CoCo 1/2/3,
-  MC-10, Alice, and clones (MX-1600, CP-400, Dragon 200-E, Deluxe CoCo).
-  ROM files are searched in a configurable rompath directory with automatic
-  extension appending (.rom, .ROM, .dgn, .DGN). Batocera sets rompath to
-  /userdata/bios/xroar/.
-
-  The romlist mechanism defines fallback filenames per ROM slot. Each machine
-  type has a default romlist that tries filenames in priority order. CRC32 is
-  computed for loaded ROMs and matched against known-good values for breakpoint
-  and feature detection, but mismatches do not prevent loading.
-
-  Machine selection: Batocera maps system names to default machines via
-  xroarGenerator.py (mc10 -> mc10, dragon64 -> dragon64, others -> coco2bus).

-notes: |
-  Ymir is a Sega Saturn emulator by StrikerX3. The libretro port by
-  warmenhoven wraps the shared ymir-core library (PR #746, not yet merged).
-  No .info file exists in libretro-core-info.
-
-  Standalone: scans configured directories recursively for files matching
-  the expected size. No specific filenames required. Identifies known ROMs
-  by XXH128 hash from an internal database (19 IPL variants, 4 CD Block
-  versions, 2 ROM carts). Unknown files are accepted if size matches.
-
-  Libretro: searches {system}/sega_101.bin, mpr-17933.bin, saturn_bios.bin
-  in order. First file found with exact 512 KiB size wins.
-
-  Batocera standalone: configgen maps IPLROMImages to /userdata/bios,
-  CDBlockROMImages to /userdata/roms/saturn/cdb/, ROMCartImages to
-  /userdata/roms/saturn.
-
-  No HLE fallback for IPL ROM. CD Block LLE is optional; falls back to
-  HLE when disabled or no ROM found. Known CDB versions: 1.04, 1.05, 1.06.
-
-  ROM cartridges: KoF95 and Ultraman shipped with physical ROM carts.
-  Auto-detected from game database when loading a disc.
-
-  Addon cartridges: 1M/4M DRAM expansion handled via core option (no files).
-
-  XXH128 hashes used for ROM identification only, not validation.
-  All file loading validates size only.
