TACTSharp

Library utilizing memory-mapped file access to speed up initial loading and have lower RAM usage compared to other libraries that load WoW's CASC storage. Made so Marlamin can extract things on their NAS without it getting resource starved.
Largely based on @bloerwald's memory-mapped file reading implementations.

Current features

• Faster build loading time and lower memory footprint compared to other solutions.
• Loads both online and local World of Warcraft installations.
• Loading of game files by ekey, ckey, ID or by name from install/root manifest or listfile (only loaded if name not in install/root).
• Ability to use a folder with CDN-structured files as a data source (similar to local WoW installs).

TODO for 1.0

• Stabilize and lock-in API usage.
• Support for encrypted products.
• Support for specifying install tag priority (so e.g. the exe for WoW China can be extracted).
• Test run on all available WoW CDN data to data starting at 6.0.
• Automated tests.

Not planned

This may change in the future, but this is currently NOT planned to be part of 1.0.

• Support for other games than WoW.
• GUI tool.

Examples

FileDataID

You can use either fdid or id modes to extract specific FileDataIDs from the client.

• TACTTool -m fdid -i 53188 extracts FileDataID 53188 from Retail WoW to ./53188
• TACTTool -m fdid -i 53188 -o "warrior terrace.mp3" extracts FileDataID 53188 from Retail WoW to ./warrior terrace.mp3

Filename

You can use either name, filename or install modes to extract files from the install manifest based on filename.

• TACTTool -m name -i Wow.exe extracts Wow.exe from Retail WoW ./Wow.exe
• TACTTool -p wowt -m name -i WowT.exe extracts WowT.exe from WoW PTR to ./WowT.exe

EKey/CKey

You can use either ekey or ehash to extract files by their EKey or you can use ckey or chash to extract files by their CKey.

• TACTTool -m ckey -i 7fa7faa0fdece01a838af3c4005f7f69 extracts CKey 7fa7faa0fdece01a838af3c4005f7f69 to ./7fa7faa0fdece01a838af3c4005f7f69
• TACTTool -m ckey -i 7fa7faa0fdece01a838af3c4005f7f69 -o BattlePetAbilityEffect.db2 extracts CKey 7fa7faa0fdece01a838af3c4005f7f69 to ./BattlePetAbilityEffect.db2

List

• TACTTool -m list -i pathtolist.txt will read pathtolist.txt and extract files to the extract folder in the current working directory.
• TACTTool -m list -i pathtolist.txt -o D:/myoutput will read pathtolist.txt and extract files to the D:/myoutput folder.

Put files to extract in a plain text file in the below format. Similar modes as above are supported. Not giving a mode or FDID assumes it is using the filename mode. An additional part can be used to set the output filename.
These are all valid lines:

install;WoW.exe
install;Wow.exe;Wow-but-I-wanted-to-rename-it.exe
WoW.exe
Wow.exe;Wow-maybe-this-name-is-better.exe
