Corrupted DOTA2 TI6 Replay Files (Match ID 2558190331)

[sanhaodashu]

Hi,
I'm attempting to re-download replays from The International 2016 (TI6), but both the ​DOTA2 Client and ​Opendota API consistently return corrupted .dem.bz files that fail decompression (tested across multiple environments: different machines, OS, networks). Example: Match ID 2558190331

Notably, Opendota’s ​match analysis endpoints can parse metadata (e.g., hero picks, events) from this replay.

Questions:

Are there ​replay file repair tools or methods to salvage corrupted .dem files ?
Are ​alternative sources (e.g., community archives, SteamCMD) available for legacy TI6 replays?
Appreciate any technical guidance!
