That is all. Just extract the .jar and shortcut into the Data folder as is and click the shortcut to look at or extract files from the .BSA's.

BSA Commander works with them as well, I decompressed them all this way.

Good stuff! Glad it retained compatibility - I consider that a gift.

Anyone know if ArchiveInvalidated is needed to override vanilla FO:NV textures? I'm considering using NMC's textures to replace some of the recycled FO3 textures in New Vegas.

yeah, you need to use archiveinvalidated.txt

On the nexus, BOTG has released high-rez type 3 female for New Vegas (already), so its a simple enough process probably.
