This is a rewrite of leppie’s spb2xml tool to work with MSFS 2024.
It decompiles compiled SimProp binary (.spb) files back to XML, so you can
read how the default visual effects, scenery objects and other assets are
built.
Summary of changes from the MSFS 2020 version:
- MSFS 2024 support
- Decodes the new visual effect input pins (a float value stored together
with a source GUID), which earlier tools left undecoded - Adds FLOAT3, OUTPUTVALUE, BEZIERCURVE and the full INPUT* type family
- UTF-8 or Windows-1252 output
- Standalone single binary, no .NET runtime required (Rust, zero dependencies)
