New in Recalbox 10.1: the Libretro PUAE 2021 core arrives on the Amiga systems.
Libretro PUAE 2021 is the "2021" variant of the libretro PUAE core, i.e. an earlier version of its code base, maintained alongside the current PUAE core. PUAE descends from P-UAE, itself derived from UAE and WinUAE.
The project is released under the GNU GPL v2 license: github.com/libretro/libretro-uae.

Per-board availability:
| Emulator | RPI3/RPI02W | RPI4/400 | RPI5/500 | OGA/OGS/RG351 | PC | RG353 |
|---|---|---|---|---|---|---|
| Libretro PUAE 2021 | ✅ | ✅ | ❌ | ✅ | ❌ | ✅ |
This core is not available on RPi5/500 nor on PC in Recalbox 10.1. On those machines, use Libretro PUAE or Libretro Amiberry.
Announced compatibility: high. Speed: high.
This core is not the one launched by default: on the boards where it is available, Libretro UAE4ARM starts first. On RPi3/RPI02W and RPi4/400, Libretro PUAE 2021 comes second in the emulator list; elsewhere you have to select it manually in the system or game options.

This declaration names the historical cores (Amiberry, PUAE, UAE4ARM): Libretro PUAE 2021 is not listed there yet. The CDTV Kickstart is still required to emulate the machine: install it exactly as you would for the other cores.

Unlike the other Amiga CDTV emulators, the extension list declared for this core is the Amiga floppy and hard disk one: it contains no CD image (
.cue,.iso,.chd,.nrg…). For CDTV CD-ROM games, use Libretro PUAE, Libretro UAE4ARM, Amiberry or Libretro Amiberry.
Games spread over several floppies can be grouped in a .m3u file listing the images in order. Recalbox 10.1 also brings support for .hdf virtual hard disks.

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.
Recalbox 10.1 enables the per-game configuration popup of the lr-puae cores by default: it lets you adjust the main settings when a game starts, without going through the RetroArch menu.
The exact list of options depends on the core version shipped with your Recalbox release.
