The emulator for the RISC CPU core of MSP430 is written in pure Elixir, following chapter 1 & 3 of the spec at https://www.ti.com/lit/ug/slau049f/slau049f.pdf
See the code in lib/elixir_ctf/domain for more details.
The C code files for the lock are in priv/level_data (there are only 4 levels right now). They are compiled using gcc-msp430 to produce hex and objdump files. See priv/level_data/build.sh for more details.
The main UI is built using LiveView. Most of the code is in lib/elixir_ctf_web/controllers/level_play_live.ex
