I don't think you can emulate it on a tiny piece of hardware; the smallest full Uxn/Varvara implementation I've seen so far is the GameBoy Advance, which has 384KiB of RAM. On the other hand, you've previously been able to emulate some pretty astonishing things on pretty astonishing hardware.
There are a lot of minor things in Uxn and Varvara that make them hard to emulate efficiently. Extensive use of self-modifying code, memory-mapped I/O, and using a stack instruction set, for example.
I'm interested to hear how you'd redesign Uxn/Varvara to be easy to emulate on some tiny piece of hardware; of everyone in the world, you're probably the best person to answer that question. Little-endian, check. What else?
