Theseus, a Static Windows Emulator

2 days ago

Theseus is a static Windows/x86 emulator using static binary translation, converting Windows executables into native code via a compiler.
The author moved from retrowin32 to Theseus after realizing the benefits of static translation over JIT and interpreter approaches, inspired partly by decompilation efforts.
Static translation offers performance and development advantages, including better optimization, debugging with native tools, and simpler integration with native system APIs.
Challenges include handling runtime code generation and dynamic control flow, but the author accepts manual intervention for specific programs as viable.
Theseus simplifies the emulation architecture, reduces runtime overhead, and has potential for WebAssembly compatibility, though not yet implemented.
The project's name, Theseus, reflects replacing all parts of the original program, raising philosophical questions about program identity and emulation accuracy.
Future ideas include manually replacing inefficient or buggy code segments in programs to improve performance or add features, leveraging modern compilers.
