TACT Parser

Parser for various TACT file formats, as they are used on the NGDP CDN.

Some other community tooling describes these as "CASC files"; but CASC refers to the virtual filesystem used by locally-installed copies of games.

Roadmap

The plan is to read enough of the the TACT files to allow ngdp-client and tact-client to download and extract WoW data files from the NGDP CDN.

This is not yet integrated with the rest of cascette, and has been tested using existing cached copies of CDN data from SimulationCraft's casc_extract.py.

• Read WoW Root, to find the file ID and MD5s of each variant of game data files (eg: .db2)

• Read encoding table, to find the BLTE file keys for a game data file MD5

• Read BLTE files, to get file content

• Read patch files
