Kaitai Struct: A new way to develop parsers for binary structures
I can't claim credit for the API and reverse engineering of the data model (https://github.com/0Liam/smm2-documentation), standing on the shoulder of giants here. But the original level viewer was a windows app (there are since a handful of web ports of it); it seemed like an opportunity to learn a few technologies (Rust, WASM). There were a lot of interesting problems, i'll do a proper write-up one day.
