Each platform's own packages were read at the revision our data pins, for every emulator and core it ships: Batocera, Recalbox, RetroPie, ROCKNIX, Lakka, RetroDECK, RetroBat and EmuDeck. Files a package installs where the emulator reads them are recorded with installed_on, and files a release bundles but a package leaves out with not_bundled_on, so each platform's pack brings what its users lack and nothing they already have. The standalone profiles never checked before were held against their releases the same way. Batocera's imame4all is the mame2000 core. The primary neogeo.zip was a 7.7 KB placeholder no platform pins and no pack served: removed, the real dumps stay in .variants.

|
Runs the original Sega Lindbergh game binaries on Linux, built and executed
|
|
as 32-bit x86. The launcher picks the game ELF, exports
|
|
LD_PRELOAD=lindbergh.so and an
|
|
LD_LIBRARY_PATH covering the loader directory, the original directory, the
|
|
game directory and ".:lib:../lib", then system()s the ELF
|
|
(src/lindbergh/lindbergh.c:315-378, 874-929). Platforms invoke it as lindbergh-loader
|
|
(Batocera package and generator, RetroBat, ES-DE find rule LINDBERGH-LOADER).
|
|
|
|
The Lindbergh hardware is emulated inside lindbergh.so with no external
|
|
firmware. Hooked open() and fopen() redirect /dev/lbb (baseboard), /dev/i2c/0
|
|
(eeprom), /dev/ttyS0 and /dev/ttyS1 (drive, ride, motion boards and card
|
|
reader), /proc/bus/pci/01/00.0 and /proc/bus/pci/00/1f.0 to /dev/zero and
|
|
answer from code (src/lindbergh/hook.c:43, 530-615, 641-853). The security board is DIP
|
|
switches and test/service lines computed in securityBoard.c:98-140, with no
|
|
keychip dump. eeprom.bin and sram.bin are created on first run and their
|
|
contents synthesised: eepromSettings.c builds every amSysDataRecord section
|
|
from constants and recomputes the CRCs (eeprom.c:33-48, baseBoard.c:60-74,
|
|
eepromSettings.c:24-120). Card_01.crd and Card_02.crd are written from a
|
|
56-byte header held in the binary (cardReader.c:227-247). lindbergh.ini and
|
|
controls.ini are optional: both fall back to compiled-in defaults and can be
|
|
emitted with --create (config.c:510-516, src/lindbergh/sdlInput.c:790-795).
|
|
|
|
The one hard external dependency is the NVIDIA Cg runtime. findLibCg() checks
|
|
LIBCG_PATH from the ini, then /app/lib32/libCg2.so, $APP_IMG_ROOT/usr/lib32/
|
|
libCg2.so, ./libCg.so and $LINDBERGH_LOADER_CURRENT_DIR/libCg.so, and exits
|
|
when none is present (src/lindbergh/shaderPatches.c:1028-1108). Cg 3.1 is a separate
|
|
requirement: the game ELFs link libCg.so and libCgGL.so, which upstream
|
|
vendors as libs/Cg-3.1.zip and installs into the runtime library directory
|
|
(scripts/appimage/make-appimage.sh,
|
|
scripts/flatpak/com.github.lindberghloader.yml:181-189, 242-245). Batocera
|
|
copies per-game Cg variants into the ROM directory
|
|
(batocera lindberghGenerator.py:1027-1050).
|
|
|
|
Shaders come from the game dump, not from the loader. cacheModedShaderFiles()
|
|
reads ../fs/shader and /data/Shader relative to the ELF, patches the Cg
|
|
source and serves the result back through the fopen, fread and ftell hooks
|
|
(shaderCache.c:474-488, 555-678, src/lindbergh/hook.c:778-808, 1140-1212).
|
|
|
|
Boot logos and console fonts were user-supplied until 2.0.1, which added
|
|
built-in copies compiled into lindbergh.so and served from
|
|
resources/logo.h and resources/font.h. The originals are read only when
|
|
DISABLE_BUILTIN_LOGOS or DISABLE_BUILTIN_FONT is set, from the game
|
|
directory (src/lindbergh/hook.c:655-744, 874-926, fread hook at 1159-1181). Batocera
|
|
exposes both switches as ORIGINAL LOGOS and ORIGINAL FONTS.
|
|
|
|
Custom cursors and crosshairs load from arbitrary ini paths with no default
|
|
name and no built-in image (crossHair.c:142-186, customCursor.c:26-33).
