Technical notes

Written for libretro by David Richardson. Intellivoice SP0256 emulation contributed by Joe Zbiciak (jzIntv), mask ROM embedded in source (src/ivoice.c:337-510, 4097-byte static array). No external ivoice ROM.

BIOS loading in retro_init() (src/libretro.c:1175-1183). Paths joined directly to system directory, no subdirectory.

loadExec() reads exec.bin as big-endian 16-bit words into 0x1000-0x1FFF. loadGrom() reads grom.bin as raw bytes into 0x3000-0x37FF.

Both files required for operation. Without them, the OSD shows "PUT GROM/EXEC IN SYSTEM DIRECTORY" and games do not run.

No hash or size validation on either file.

No ECS support. No ecs.bin loading code in the source.

Per-game controller overlays are read from freeintv_overlays/<rom>.png (or .jpg) in the system directory, only when the multi-screen option is on (src/libretro.c:278-280, 294). Without one the core draws the keypad image embedded in the binary (src/libretro.c:321-325).
