Simon once posted the format for Stamp files, but that is an old version of the format and the current version has support for "decorations" as well as other possible additions. Can a developer who's familiar with the current format please post it. Thanks in advance.
It isn't a secret, several decoders have been made by other users, I have posted it before and it also in the source code (look for parse_save and build_save in main.c)
You only posted the old version. The more recent version isn't quite the same. The most recent version can't be read correctly with my TPT save reader program (based on the older format).
