Uxn is a stack-machine with 32 instructions.

Uxn is a portable 8-bit virtual computer inspired by forth-machines, capable of running simple tools and games programmable in its own unique assembly language.

It was designed with an implementation-first mindset with the goal of targeting salvaged computers, the distribution of Uxn projects is akin to sharing game roms for any classic console emulator.
