A Ghidra extension that turns programs back into object files
Hi all, I've been working on tooling that can reverse the work of a linker. It allows one to take bits and pieces of an executable and delink them into working object files, which can then be reused as-is to make new programs or libraries, without having to decompile or disassemble them first. The readme has links to my blog demonstrating some of the use-cases. The most impressive one so far is making a port of a ~100 KiB Linux a.out i386 program to a native Windows PE i386 executable, despite not having access to its original source code or even decompiling it. Currently, 32-bit i386 and…

A Ghidra extension for exporting parts of a program as object files2024 · github.com · ▲304This Ghidra extension unrelocates machine code through analysis and then synthesizes a working object file from a listing selection. It effectively turns computer programs into Lego bricks, to be torn down into pieces and reused into something new. It supports the COFF and ELF object file formats, for the x86 and MIPS architectures. It has been successfully used on Linux, Windows and PlayStation executables. One user report is on a commercial video game from 2009 with a ~7 MiB Windows executable written in C++: it was delinked without its C runtime library and then relinked into a new…

Ghidra Plays Mario2023 · github.com · ▲207I've been exploring new ways of testing Ghidra processor modules. In this repo, I was able to emulate NES ROMs in Ghidra to test its 6502 specification, which resulted in finding and fixing some bugs. Context: Ghidra is used for reverse engineering binary executables, complementing the usual disassembly view with function decompilation. Each supported architecture has a SLEIGH specification, which provides semantics for parsing and emulating instructions, not unlike the dispatch handlers you would find in interpreters written for console emulators. Emulator devs have long had extensive test…
BiTE – Cross-platform executable viewer and reverse engineering tool2024 · github.com · ▲176Hey everyone! I’m excited to share a project I’ve been working on throughout my university studies. It’s called BiTE (https://github.com/WINSDK/bite) and it's a tool primarily focused on being an executable viewer with reverse engineering capabilities. BiTE supports Windows, MacOS, and Linux, along with their associated executable formats. It’s also capable of parsing and displaying debug information using DWARF/PDB formats, which I hope will be useful even for just comparing codegen. I’ve put a lot of effort into this and it's the first time I'm releasing something…
I ported Tree-sitter to GoFeb 2026 · github.com · ▲222This started as a hard requirement for my TUI-based editor application, it ended up going in a few different directions. A suite of tools that help with semantic code entities: https://github.com/odvcencio/gts-suite A next-gen version control system called Got: https://github.com/odvcencio/got I think this has some pretty big potential! I think there's many classes of application (particularly legacy architecture) that can benefit from these kinds of analysis tooling. My next post will be about composing all these together, an exciting project I call…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
