Technical notes

ARM-optimized Amiga emulator by TomB, ported to libretro by Chips-fr. Based on an older uae4arm version, intended for low-powered ARM hardware where PUAE cannot maintain full speed.

Core options expose three models: A500, A600, A1200. Each selects its Kickstart ROM automatically. Extended ROMs (CDTV/CD32) can be set via .uae config files but CD32/CDTV hardware emulation is absent from this port (no akiko chip, CD support listed as missing).

Built-in AROS Kickstart replacement used as fallback when no ROM is found.

Cloanto-encrypted ROMs require rom.key in the system directory.
