Drifblim is a Uxntal assembler, written in Uxntal.
The assembler is written in less than 400 lines of Uxntal, it's designed to help bootstrap the Uxn ecosystem. The goal is for Driflim's source code to be released as a print-friendly document, along with its assembled hexadecimal data and the napkin definition of the virtual machine.

Since this assembler is written in the language it is assembling, it creates a chicken-and-egg problem. You have two choices, download a pre-assembled drifblim.rom(1.2kb), or use uxnasm.c.
It will not support macros or includes. Instead, a separate pre-processor rom might be considered.
Drifblim is strong enough to lift Pokémon or people but has no control over its flight. This causes it to drift with the wind and end up anywhere.

This is the hexadecimal data of the drifblim assembler, I am keeping a copy of it here just in case.
