About a year ago, I started working on disassembling the NES game Faxanadu. The goal was to fully understand and document the game, and to produce the most thorough understanding of the game yet. It's been fascinating. The game has a two binary scripting languages (one for interactions with items and NPCs, one for NPC/enemy behaviors) and a very interesting graphics rendering layer. At this point pretty much the entire game is well-understood.
Based on this work, there's now a new suite of tools for producing games under the Faxanadu engine, new major mods built with all this, and some work on a modified ROM better built for porting and modding.
Disassembly is here: https://chipx86.com/faxanadu/
And I've been blogging about it at https://chipx86.blog/
Building a universal web-based retro game modding tool along with that work called Nostalgia Studio. The idea is that there's a core foundation for representing game state and building editors, a platform-specific layer for representing things like the NES APU and PPU state, and then game-specific implementations that populate state for two layers below.
Those are the hobbies.
Day job, I work on Review Board (https://www.reviewboard.org), one of the original code review products. We just released Review Board 8, which was a pretty large project (we built Office document review, browser-native spell checking in CodeMirror, a new interdiff filtering algorithm, Forgejo integration, and a bunch of other things).
So now I'm working on plans for Review Board 9, with a goal of releasing within the next 4-6 months. Got some thoughts on how the review process can be rethought for this current era of development, so starting work on that.

I noticed a similar optimization path with skills, where I now have subagents to analyze the performance of a previous skill/command/hook execution, triggered by a command. I've pushed this to my plugin marketplace https://github.com/athola/claude-night-market

mira
Self-hosted AI code reviewer with indexed PR reviews, walkthroughs, vulnerability scanning, dependency graphs, custom rules, and a learning loop. (by miracodeai)
Project mention: Ask HN: What tools are you using for AI-assisted code review? | news.ycombinator.com | 2026-06-19Co-founder of Mira [1] here.
This is exactly what we built Mira for. It's self-hosted, bring-your-own-model/BYOK, and most importantly, open source.
You point it at your own API keys (e.g. OpenRouter or a local model) so nothing leaves your infra, and it runs as a code reviewer on PRs.
It's also ridiculously quick at reviewing (benchmarks at ~77s) because your PRs aren't sitting in a queue on a cloud somewhere (alternatives are > 5 minutes)
We're working really closely with our users to build the best possible code reviewer. Feedback and contributions are highly encouraged.
