 This assembler is written in the language it is assembling, creating a chicken-and-egg problem. You have two choices, download a pre-assembled [drifblim.rom](https://rabbits.srht.site/drifblim/drifblim.rom)(1300 bytes), or use [uxnasm.c](https://git.sr.ht/~rabbits/uxn/tree/main/item/src/uxnasm.c).
 
 ```sh
-# from uxnasm

 uxnasm src/drifblim.tal bin/drifblim.rom
 # from drifblim.rom

 If do not wish to assemble it yourself, you can download [drifblim.rom](https://rabbits.srht.site/drifblim/drifblim.rom).

 _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._
