This app can be used to download Gravitrax courses and see information about them, if you know the codes used in the app. It is a web application, currently deployed at: https://murmelbahn.fly.dev
Some URLs that are supported:
- Dump: https://murmelbahn.fly.dev/course/GDZJZA3J3T/dump
- Bill of Material (BOM): https://murmelbahn.fly.dev/course/GDZJZA3J3T/bom
- This one takes a query parameter called
formatwith values ofcsv,rustorjson(the default) csvoutput is compatible with the GraviSheet
- This one takes a query parameter called
- Raw data: https://murmelbahn.fly.dev/course/GDZJZA3J3T/raw
- This is the data as it comes from the Ravensburger API (only base64 decoded)
I used the ImHex editor to reverse engineer the data format.
I did include the schema so you can look at files yourself if you like.
It can be found in the file imhex-schema.txt in this repository.
Ravensburger changed the file format multiple times.
This app can only process the latest three formats (anything after 2020, the introduction of "Pro").
Earlier versions could - in theory - be supported but I didn't find many tracks with those formats out there with the exception of courses between 2019 and 2020, I might add support for this later.

- Thank you very much Chris Fuchser for all your help in understanding Gravitrax and testing this program
- WerWolv for the fantastic ImHex editor. That was a fun week to play around with!
