Recently developer SockNastre made available on Github both a Frost4 Toolkit for modifying the proprietary Frostbite engine on PS4 alongside some BethesdaArchive2 GNMF tools to read / write in Bethesda's proprietary GNMF (BA2) archive format used on PlayStation 4 for Mirror's Edge Catalyst and Fallout 4 video game modders to enjoy. :cool:

Download: Frost4-Toolkit-master.zip / Frost4 Toolkit GIT / BethesdaArchive2.GNMF.Packer.v1.1.2.0.zip / BethesdaArchive2 GNMF GIT

These tools from @SockNastez come following the Fallout 4 PS4 Mods, Fallout 4 PS4 EBOOT.BIN ELF Patcher and Fallout 4 PC Mods on PS4 Tutorial Video previously released.

From the README.md: Frost4-Toolkit

Info


Currently very BETA, current purposes are data analysis but the tool can be used to browse the ebx/res filesystem of Frostbite on PS4, specifically for Mirror's Edge Catalyst

Requires .NET Framework 4.7.2

Features
  • Can browse the virtual filesystem of Frost4.
  • Able to extract ebx and res.
  • Has a profile system to support separate game profiles.
Credits
  • Thanks mirrorsedgefan for creating the awesome Frost4 logo.
And from the other README.md: BethesdaArchive2 GNMF

First release of packer tool, just allows packing. For unpacking the tool BSA Browser (With .BA2 Support) supports unpacking the GNMF BA2 format.

Requires .NET Framework 4.7.2

Features
  • Can pack single-chunk GNMF BA2 archives.
  • Drag & drop for files and folders to add quickly into archive.
  • EntryString editor for user-friendliness.
  • Allows for modification of textures on Fallout 4 PS4.
F.A.Q

Q: How can we open GNMF BA2?
A: The BSA Browser tool by AlexxEG (see credits) supports opening GNMF BA2.

Q: Why only one chunk? Does that matter?
A: I have not researched multi-chunk GNMF BA2 but for authenticities sake I will try to include the option in a future release. From experience one chunk will do fine, but it can be assumed with a lot of high resolution textures multi-chunk would help.

Credits
  • Thanks to AlexxEG for help with understanding original BA2 format.
  • Thanks to derwangler for getting me a proper CRC32 hashing class.
  • DotNetZip library for zlib compression.
Cheers to @HydrogenNGU on Twitter for the heads-up on these earlier! 🍻
