# Full HLE PS2 emulator by Jean-Philip Desjardins.
# All PS2 subsystems are reimplemented in C++: EE kernel (PS2OS.cpp),
# IOP BIOS modules (IopBios.cpp), GS, SPU2, VU units.
# The libretro core never calls RETRO_ENVIRONMENT_GET_SYSTEM_DIRECTORY.
#
# LoadBIOS() exists in Ee_SubSystem.cpp:832 but is commented out at line 232.
# IOP modules (SIO2MAN, PADMAN, MCMAN, MCSERV, CDVDMAN, CDVDFSV, etc.)
# are all HLE-replaced via m_hleModules in IopBios.cpp:279-290.
# _IOP_EMULATE_MODULES=1 is unconditionally defined in CMakeLists.txt:24.
#
# source_ref: Source/ee/Ee_SubSystem.cpp:232 (LoadBIOS commented out)
# source_ref: Source/iop/IopBios.cpp:279-290 (HLE module table)
# source_ref: Source/PS2VM.cpp:483-537 (ResetVM — no BIOS loading)
# source_ref: Source/ui_libretro/main_libretro.cpp:546-568 (retro_init — no file I/O)
