exclusion_note: >
Uxn/Varvara is a software-defined stack machine with 64KB of memory.
The VM has no firmware or BIOS. ROMs compiled from Uxntal assembly are
loaded directly via libretro game_info. The .info declares no firmware.
notes: >
Libretro wrapper around the zuxn library (Zig implementation of the
Uxn/Varvara spec by Hundred Rabbits). The file device in Varvara handles
ROM-initiated I/O but does not load system files from the system directory.
