Technical notes

Frozen snapshot of bsnes v085 downgraded to C++98 for old compilers (PS3). Performance profile only. is_experimental=true.

NEC DSP and Hitachi DSP firmware loaded from the ROM directory, not system_dir. Path: dir(interface->path(Slot::Base, ".dsp")) + firmware_name from game XML markup. interface->path() returns ROM basename + hint. ref: snes/cartridge/markup.cpp parse_markup_necdsp, parse_markup_hitachidsp ref: snes/libretro/libretro.cpp Interface::path()

RETRO_ENVIRONMENT_GET_SYSTEM_DIRECTORY is never called. No file I/O targets system_dir anywhere in the codebase.

Core continues without DSP firmware but coprocessor games won't function.

No BIOS or firmware files required.

Why no files

The .info declares firmware_count=0. DSP firmware (NEC uPD7725/uPD96050, Hitachi CX4) is loaded from the ROM directory via game XML markup, not from system_dir. RetroArch cannot pre-populate firmware in the ROM directory. Upstream byuu.org is defunct, and this libretro port is the preserved v085 code.
