WinUAE

WinUAE emulates Commodore Amiga, Commodore Amiga CD32 and Commodore CDTV. It reads 10 files, 6 of them required: without a required file it does not start games. A required file is needed only by the machines that use it. It recognises a file by its contents, so any file name works. Each file below cites the line of source code that reads it.

Technical notes

Amiga emulator for Windows by Toni Wilen. The Kickstart is the file named by kickstart_rom_file in the configuration. When it is absent the loader tries roms/kick.rom, kick.rom, ../shared/rom/kick.rom and ../System/rom/kick.rom under the data path, then guesses from the scanned ROM list (memory.cpp:2038-2071). When nothing loads it reports the missing ROM and boots the built-in AROS replacement (memory.cpp:3058-3063). Loaded ROMs are matched against the ROM table only to name them and check the CPU they need. An unknown ROM is still used (memory.cpp:3064-3101).

The ROM list is built by scanning KickstartPath and the default ROM paths when no DetectedROMs list exists yet. Every file below 10000000 bytes whose extension is rom, bin, adf, key, a500, a600, a1200, a3000, a4000, cd32 or U followed by a digit is identified against the ROM table, whatever the rest of its name (od-win32/win32.cpp:5385-5404, od-win32/win32gui.cpp:1747-1772, od-win32/win32gui.cpp:1829-1876, od-win32/win32gui.cpp:1974-2105). The guess step takes a scanned ROM whose file name matches the configured one (rommgr.cpp:2428-2461). The Kickstart entries below are named after other profiles' names for the same dumps: the code opens none of those names. kickstart_ext_rom_file is opened as given, and a missing extended ROM only raises a notice (memory.cpp:1833-1849). The machine then starts on the Kickstart alone with nothing mapped in place of the extended ROM, and the AROS replacement is used only when the Kickstart itself is missing (memory.cpp:3055-3063). The CD drivers and CD boot code are resident modules of the extended ROMs: cdstrap, cd.device and cdfs.library in the CD32 ROM, cdtv.device, cdfs.library and cdstrap in the CDTV ROM. The CD32 and CDTV Kickstarts carry none. The CD32 quickstart model and the base CDTV model have no floppy drive (cfgfile.cpp:9374-9378, 9404-9405), and both ask for the extended ROM (cfgfile.cpp:9389-9394, 9413-9422), so without it no CD is read or booted.

CDTV and A600/A1200 internal devices are enabled with :ENABLED, which needs no ROM file. Cloanto encrypted ROMs are decoded with rom.key, searched in the configured key path, the ROM path, roms/, the data path, ../shared/rom/ and next to the Kickstart file (rommgr.cpp:1459-1535). Without it an encrypted ROM fails to load (rommgr.cpp:1724-1732).
