Technical notes
AppleWin is an Apple II/IIe/II+ emulator. The libretro port embeds all ROM images directly into the compiled binary via a CMake resource system (resource/CMakeLists.txt -> apple2roms static library -> apple2roms_data.h). The GNUFrame::GetResourceData() function serves ROMs from this compiled-in map. No external BIOS/firmware files are needed.
The core never calls RETRO_ENVIRONMENT_GET_SYSTEM_DIRECTORY and the official applewin_libretro.info has zero firmware entries.
Supported machine types (via core option applewin_machine): Enhanced Apple //e, Apple ][ (Original), Apple ][+, Apple ][ J-Plus, Apple //e, Pravets 82, Pravets 8M, Pravets 8A, Base64A, TK3000 //e
Supported extensions: bin, do, dsk, nib, po, gz, woz, zip, 2mg, 2img, iie, apl, hdv, yaml, m3u
supports_no_game: true (can boot without content)
No BIOS or firmware files required. Generated on 2026-03-25T14:56:43Z
