New in Recalbox 10.1: the Libretro Amiberry core arrives on the Amiga systems. This release also fixes Amiga CD32 BIOS detection.
This core is announced as experimental in Recalbox 10.1: games may refuse to start, crash, or show graphical and sound glitches. If a game misbehaves, fall back to Libretro PUAE, Libretro UAE4ARM or Amiberry.
Libretro Amiberry is the libretro core port of Amiberry, an Amiga emulator optimised for ARM machines, itself derived from UAE and WinUAE. It lets you run the Amiberry engine inside RetroArch, and therefore benefit from shaders, rewind and the configuration shared with the other cores.
Amiberry is free software released under the GNU GPL license: github.com/BlitterStudio/amiberry.

Per-board availability:
| Emulator | RPI3/RPI02W | RPI4/400 | RPI5/500 | OGA/OGS/RG351 | PC | RG353 |
|---|---|---|---|---|---|---|
| Libretro Amiberry | ❌ | ✅ | ✅ | ❌ | ✅ | ✅ |
This core is not built for RPi3/RPI02W, nor for the Odroid Go Advance/Super and RG351. It is however the only Amiberry core available on PC, since the standalone Amiberry is not shipped there.
Announced compatibility: high. Speed: high.
On RPi4/400, Recalbox raises this core to the highest priority level for the Amiga CD32; on the other boards it sits at the end of the list and has to be picked manually in the system options or in a game's advanced options.

Those declarations name the historical cores: the "Amiberry" entry refers to the standalone emulator, and Libretro Amiberry is not listed there yet. The CD32 Kickstart is still required to emulate the console: install the files exactly as you would for the other cores.

Unlike the other Amiga CD32 emulators, the extension list declared for this core is the Amiga floppy, WHDLoad and hard disk one: apart from
.chd, it does not include CD images (.cue,.iso,.nrg,.mds,.ccd). For a CD32 game in.cue/.isoformat, use Libretro PUAE, Libretro UAE4ARM or Amiberry.
Recalbox 10.1 also lets you launch .lha archives (games pre-installed in the WHDLoad format) directly with Amiberry.

While in game, press HOTKEY + B to open the RetroArch menu, then go to the Options (Core Options) section to reach the emulator's own settings. Settings can be kept for the whole system or for one specific game.
The options exposed by Libretro Amiberry mainly cover the emulated Amiga model, the video standard (PAL/NTSC), image cropping and drive speed. Since the core is new and experimental in Recalbox 10.1, the exact list changes from one release to the next: browse the Options menu to see what is available on your system, and leave the default values alone unless a specific game misbehaves.
