Batocera 43.1 builds libretro/ps2 at 416291a with 001.bios-dir.patch and Recalbox 10.1.1 builds it at 9485a53 with 0001-recalbox-paths.patch. Both patches move the BIOS scan from pcsx2/bios to ps2, and Recalbox also moves the data root to system/ps2. Each build gets its own built_by profile: lrps2-416291a under Batocera's pcsx2 name, lrps2-9485a53 under Recalbox's ps2 name. A platform's own build now answers for its own build mode only on a dual_mode_cores name, so Batocera keeps standalone PCSX2 beside its libretro build.

notes: |
|
|
Recalbox installs the build as ps2_libretro.so (Recalbox
|
|
package/libretro-ps2/libretro-ps2.mk:31-33) and lists it as the libretro
|
|
core ps2 of the ps2 system (Recalbox
|
|
package/recalbox-romfs2/systems/ps2/system.ini:65-69).
|
|
The library version is the short commit hash git reports at build time
|
|
(cmake/BuildParameters.cmake:4-9, libretro/main.cpp:1424-1428).
|
|
|
|
Its patch moves the BIOS scan from pcsx2/bios to ps2 below the system
|
|
directory (libretro/main.cpp:1807), the data root from system/pcsx2 to
|
|
system/ps2, so resources are read from ps2/resources
|
|
(libretro/main.cpp:1911-1913), the BIOS folder default to
|
|
/recalbox/share/bios/ps2, the same folder on Recalbox, and memory cards to
|
|
/recalbox/share/saves/ps2 (pcsx2/Pcsx2Config.cpp:1042-1043, 1061-1062).
|
|
|
|
BIOS detection is filename-agnostic: ps2/ is scanned for any file between
|
|
4 and 8 MB with a RESET and a ROMVER romdir entry, no hash is checked, and
|
|
the list fills the pcsx2_bios core option whose default is the first BIOS
|
|
found (libretro/main.cpp:1801-1839). retro_load_game refuses to start when
|
|
no BIOS was found (libretro/main.cpp:1928-1932). The companion files take
|
|
their path from the selected BIOS.
|
|
|
|
The DEV9 hard disk image is user storage the core creates, not a file to
|
|
obtain.
