What people are saying

For anyone who regularly has to look at/analyze binary files, i highly recommend ImHex [1]. Its a hex editor built with imgui and has a lot of built in tools. Imo the best…

My experience with parsing undocumented binary formats is with Skia's skp files. Unfortunately they don’t publish any docs regarding the format. Instead I relied on their source code (which is very convoluted), and in that process I discovered two tools which proved pretty useful: - Kaitai [1], which takes as input a YAML file and can parse binary files based on it (and even generate parsers). - ImHex [2], which has a pattern language [3] which allows parsing, and it seems more powerful than what Kaitai offers. I stumbled upon some limitations with it but it was still useful. [1]: https://kaitai.io/ [2]: https://github.com/WerWolv/ImHex [3]: https://docs.werwolv.net/pattern-language/
In Parsing an Undocumented File Format
My, that is very useful. I have been out of the bit land for a very, very long time -- the last of my assembly programs are old enough to drink -- but I am increasingly finding myself running hexdump again and it's not a great experience. I expected better in 2023 and here it is. I will explore but https://github.com/WerWolv/ImHex/blob/c2e023f567d4e838ea69e6... this makes me super-duper hopeful. UTF-8 capable ex viewer, that'd be handy.
In Hexyl: A command-line hex viewer with colorized output
I don't know how popular Gravitrax is state-side. For those who don't know, it's a popular marble run system with dozens of extensions from Ravensburger[1] (see what can be build in a recent video here[9]), our kids love it! And a Junior version for kids 3+ is coming out this year. It comes with a free app that can be used to build courses and then also share those courses via a simple short code. The app can also display all the tiles you need to build a course. What is not possible is to list available courses or check whether you have enough tiles to build a specific course. Chris Fuchser (The Masked Marble on Youtube[2]) built something called Gravisheet[3] which is a Google Sheet where he collects codes from the app and also lists which tiles you need and so on. This is awesome and a great start! Unfortunately, it requires a lot of m

anual work so at christmas when my kids (ahem...) got their first set I got started reverse engineering the file format Ravensburger uses and built a small library/site to display information about it. The source code can be found on Github[4] and the site is also hosted on a free fly.io machine[5]. You can already see a JSON dump of the binary file contents[6] and also get a Bill of Materials[7] for a course. On the frontpage you can say which sets or extensions you have and get a list of courses. This is all very rudimentary, mostly because of lack of time and lack of frontend skills but maybe it is useful to someone. I'd love feedback (and contributions)! Tech stack: - Rust backend with Axum - Storage in Postgres - Frontend in Svelte The ImHex editor was incredibely helpful in reverse engineering the format[8]! Thank you very much for the author, he was very helpful as well.
