Ouroboros

Ouroboros is a Rust decompiler that recovers structure with symbolic execution and constraint tracking. It tracks path constraints, register and memory deltas, dominators, and SESE regions, then forms if/else, loops, and early exits. cargo build --release builds it, and cargo run --release opens the egui interface. File, Open accepts a PE32 or PE32+ binary. Press D on the first byte of an instruction to disassemble until a NOP or an invalid instruction, then press F on the function start to decompile it.
