A linux native installer for MPI packages (TTW, BSA Decompressors, so far only tested TTW and FNV/Oblivion Decompressor). As a note this will not line up with 17GBs output it should be around 18GBs.

To run it all you need to do is either double click it and allow executing, or chmod +x mpi_installer_gui.

You can also download the the tool through Nexus if you prefer. https://www.nexusmods.com/site/mods/1657

If you want to support the things I put out, I do have a Ko-Fi I will never charge money for any of my content. Discord

Where to get MPI files?

TTW: https://mod.pub/ttw/133/files - need to make an account and download the latest Tale of Two Wastelands file. Extract it and the mpi file will be inside.

FNV BSA DECOMPRESSOR: https://www.nexusmods.com/newvegas/mods/65854

OBLIVION BSA DECOMPRESSOR: https://www.nexusmods.com/oblivion/mods/49652
