 - **firmware** - system software loaded by a console at boot; used interchangeably with BIOS in this project
 - **HLE** - High-Level Emulation; software reimplementation of BIOS functions, avoids needing the original file

 - **platform** - a distribution that packages emulators (RetroArch, Batocera, Recalbox, EmuDeck, etc.)
 - **core** - an emulator packaged as a libretro plugin, loaded by RetroArch or compatible frontends
 - **profile** - a YAML file in `emulators/` documenting one core's BIOS requirements, verified against source code
