Could you build this?
No Recreating a complex 3D vehicle simulator engine from scratch in Rust with full backward compatibility for legacy proprietary file formats, custom scripting, and physics requires extensive systems and graphics engineering.
What it would actually take: Stack: Rust with wgpu/Vulkan/DirectX 12, custom physics integration (PhysX or Rapier), multi-threaded tile streaming, and custom Pascal/Delphi legacy script interpreters. Hard parts include reverse-engineering dozens of undocumented OMSI file formats (.cfg, .sco, .sli, .hof), implementing deterministic bus physics/drivetrain dynamics, and creating a robust cross-platform renderer that matches legacy DirectX 9 behavior on modern graphics APIs.
