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!
