FreeMote
Managed EMT/PSB tool libs.
About PSB
FreeMote is a set of tool/libs for M2 Packaged Struct Binary file format. The file header usually starts with PSB/PSZ/mdf,
and the file extensions usually are .psb|.psz|.mdf|.pimg|.scn|.mmo|.emtbytes|.mtn|.dpak.
However, there are some other file formats using the same extensions. They are NOT supported:
.psb: PlayStation Binary (PS3) | PhotoShop Big (Photoshop).mdf: Mirror Disc File (Alcohol 120%) | Primary Data File (MSSQL).mtn: Motion File (Live2D)
Before submitting an issue or asking a question, please check your PSB file header with a hex editor.

Build
This project requires VS 2022 and .NET 4.8 to build.
FreeMote.Plugins / FreeMote.Plugins.x64 require a MyGet feed to get external libs made by us. If you don't need FreeMote Plugins, you can unload Plugins projects and remove them from other projects' reference.
To install our own nuget packages, add this feed to VS:
