Technical notes

Amiberry is an Amiga emulator based on WinUAE, available as both standalone and libretro core. No built-in kickstart — requires a real Kickstart ROM or external AROS replacement files (aros-ext.bin + aros-rom.bin).

Libretro core option "amiberry_kickstart" overrides ROM selection: auto, kick.rom, kick13.rom, kick20.rom, kick31.rom, kick205.rom, kick40068.A1200, kick40068.A4000, cd32.rom, cdtv.rom. "auto" selects per model. ref: libretro/libretro.cpp:558,621-640

Libretro ROM search directories (in order): save_dir/Kickstarts, system_dir/Kickstarts, system_dir/save-data/Kickstarts, system_dir. ref: libretro/libretro.cpp:2722-2742

Standalone ROM path: configurable via amiberry.conf "rom_path" setting. Batocera sets this to /userdata/bios/amiga/. Fallback search order: {home_dir}/roms/kick.rom, {home_dir}/kick.rom, ../shared/rom/kick.rom, ../System/rom/kick.rom, then ROM database guess. ref: src/memory.cpp:2030-2072

ROM identification uses SHA1 against WinUAE database (340+ entries) but does not reject unknown ROMs. Cloanto encrypted ROMs supported with rom.key. ref: src/rommgr.cpp:111-1100,1731-1787

Munt MT-32/CM-32L emulation compiled in (WITH_MIDIEMU). ROMs loaded from mt32-roms/ subdirectory of the ROM path. Split ROM pairs supported (e.g. pcm_mt32_l.rom + pcm_mt32_h.rom). ref: src/midiemu.cpp:82-157

Keyboard MCU emulation (keyboard_mode setting) loads MCU ROMs via ROM database scanning. Three MCU types supported: 6570-036 (A500/A600/A1000), 68HC05 (A1200), D8039HLC (A2000). ref: src/kbmcu/keyboard_mcu_6500_1.cpp:385, keyboard_mcu_6805.cpp:544, keyboard_mcu_d8039hlc.cpp:235

WHDLoad autoboot requires whdboot/ directory with boot-data.zip, WHDLoad, AmiQuit, JST, whdload_db.xml. These ship with the standalone build but must be obtained separately for the libretro core. ref: src/osdep/amiberry_whdbooter.cpp:1380-1565
