Red Dead Redemption 2

With OpenIV 4.0 the development team introduces very basic level of support for Red Dead Redemption 2. First of all, currently, there is no editing capabilities. With OpenIV 4.0 you will not be able to edit any RDR 2 files.

Since this is the first release of OpenIV with Red Dead Redemption 2 support, available features also very limited. With OpenIV 4.0 you can:
  • Open and view RDR 2 RPF archives. (Not all file names are available, see below)
  • Open and view RDR 2 Textures (.ytd)
  • Open and view RDR 2 META/PSO files (.ymt, .ymf, .yas, .ych, .ymap .ytyp)
  • Open and listen to RDR 2 Audio files (.awc)
  • Open and view RDR 2 Language files (.yldb)
  • Support for Red Dead Redemption 2 will be expanded in the future versions.

RDR 2 RPF Archives support

Few things you need to know:
New RPF8 archives does not have names for their entries, only hashes;
It is possible to harvest file names from the game itself. Just like GTA V, RDR 2 has many META, XML and PSO files that contain names of the files and archives. OpenIV has already some archives where all the file names are known.
Currently OpenIV 4.0 has a very limited database of the file names, OpenIV team is hoping to grow list of the known names with every new update in the future.

RDR 2 META/PSO support

Unlike GTA V, with RDR 2 OpenIV is using different approach for supporting PSO files. Currently you are able to open and view all PSO files in XML form. However, for the most of those files many names and strings are missing. The format of the resulted XML is also not finished yet, so the game will not be able to load those files in the XML form as you can do with some files in the GTA V.

There is a lot of data in the PSO files that needs to be analyzed, many file names can be mined from them. OpenIV team will do this in the future updates. For now, it is just basic support for you to research.

In the future releases OpenIV is going to merge our GTA V and RDR 2 PSO code so it will be possible to view all the files in GTA V and provide editing capabilities for RDR 2 PSO files.
