I run a website that serves as a league for a small community of players (somewhere around 100 active players) for a custom map on StarCraft. A necessary component of the league is the ability to parse replays that are uploaded and provide game statistics. Only the replay header information is necessary.
From my 1.18 testing, it seems as though the replays are not backwards compatible with 1.16. In particular, the replay header, which previously used a variant of PKWARE's implode algorithm for compression, now uses something different. As a result, I am not able to parse 1.18 replays, and this would be fatal to the league, and possibly to our small community. A workaround has been prepared that entails manual watching of replays and filling in the necessary information, but this is not sustainable in the long run.
I have been trying to find out what compression algorithm this is, or how to decompress, with no luck. Is there anyone who has this information? Is it one of Blizzard's secrets or can this be public knowledge? If I contacted Blizzard directly, what are the chances that they would provide this information?
Thanks and regards,
