Each PCSX2 fork declares how its LoadBiosVersion reads the table:
the strncmp length on RESET, the NUL test on names, EXTINFO, and what a
read past the end does, from the source at the pin or the shipped
libemucore.so for NetherSX2 and its Turnip builds. The Recalbox libretro
PCSX2 and PCEE2 check no size, so their 4 to 8 MB bounds are gone, and
the PCEE2 and ARMSX2 arcade images require the COH-H zone.
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.
