Do not install this mod if you're using game version 1.10.980 or later. It's redundant.
Backported Archive2 Support System replicates the updated archive loading code used in Fallout 4's 1.10.980 patch. This allows old game versions to seamlessly load newer archive files without crashing. Equivalent to Skyrim's BEES.
Pre-existing downgraded 1.10.163 versions of Fallout4.exe and steam_api64.dll. All other files (ESP, ESL, ESM, BA2, etc) may be safely upgraded to the latest game version. GOG Galaxy users need Galaxy64.dll in place of steam_api64.dll.
Custom Menu Mods
For those using custom menu or interface mods, set this plugin to load before others. MainMenu.swf should be overwritten on purpose. Alternatively, you can delete the included MainMenu.swf file. The new bethesda.net menu isn't compatible with the old game version.
