Technical notes

Frozen snapshot of Snes9x 1.43 via CATSFC (NDS/PSP port by ShadauxCat/Nebuleon). SPC700 IPL ROM (64 bytes) embedded in globals.c:191 as APUROM[64]. DSP-1 ROM data (1024 x uint16) embedded in dsp1emu.c:8 as DSP1ROM[1024]. All coprocessors (DSP-1/2/4, CX4, ST010/011/018, SuperFX, SPC7110, SA-1, OBC-1) are pure HLE. The core never calls GET_SYSTEM_DIRECTORY and performs no file I/O from the system directory.

No BIOS or firmware files required.

Why no files

all coprocessor ROMs embedded in binary; no system_directory access
