No BIOS or firmware files required. This core is self-contained.
Fork of Snes9x ~2005, optimized for slow hardware. NOT identical to snes9x — different firmware behavior.
All coprocessor data is HLE with static ROM tables embedded: DSP1: DSP1ROM[1024] in source/dsp1.c:6 DSP3: DSP3_DataROM[1024] in source/dsp3.c:7 No external DSP/ST/CX4 firmware files needed.
BS-X: path constructed in source/bsx.c:873 as romdir/BS-X.bios (relative to ROM directory, NOT system_dir). No RETRO_ENVIRONMENT_GET_SYSTEM_DIRECTORY for firmware loading.
firmware_count absent in .info (= 0). Confirmed in source.
