Technical notes

SAM Coupe emulator by Simon Owen. Port based on old pre-1.0 SimCoupe codebase. Experimental, incomplete (no sound, partial input).

SAM Coupe ROM v3.0 and SAMDOS 2.0 embedded in the binary (SAMROM.h, SAMDOS.h). HDBOOT patches for Atom Lite also embedded (HDBOOT.h). The libretro wrapper never accesses the system directory.

Upstream v1.2.x loads external resource files (samcoupe.rom, sp0256-al2.bin for VoiceBox speech synthesis). The libretro port lacks VoiceBox/SP0256 support (commented out in IO.cpp).

No BIOS or firmware files required.
