I'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…

This is a long-running personal project I've had to write an optimizing compiler from scratch. Everything was done by me, including the lexer/parser, SSA-based IR, high-performance data structures, and code generator. Originally I wasn't targeting the NES. It started as a scripting language, then it morphed into a C++ replacement, and then finally I turned it into what it is today. The large scope of the project and colorful history means it's still a little rough around the edges, but it's now working well enough to post.

I am proud to present my solo hobby project NAND. This year-long undertaking follows the completed Nand to Tetris course, but ported to the web with its own runtime, user interface, and IDE. Using the "Load example program" selector, you can try out some programs I wrote on NAND's emulated hardware such as 2048, a genetic algorithm, and a manual stack overflow to corrupt the screen. Check out NAND at https://nand.arhan.sh Additionally, I've authored an extensive writeup about the project. Read about it on the GitHub repository's readme.

Hi folks! I know NES emulators have been implemented countless times, in practically every language imaginable. However, having an LLM fully replicate the spec purely from memory—without referencing existing code—is still a significant challenge. It requires the underlying model to have strong anti-hallucination capabilities and solid long-term planning to keep from going astray. Because of this, building an NES emulator makes for an excellent LLM stress test. Here is how the emulator was built: Data Gathering: I asked Codex to download the necessary developer manuals and test suites. It was…

A while back I wrote a CHIP-8 emulator (which is considered the Hello, World! of emulators and is more accurately a virtual machine since historically CHIP-8 was an interpreted language running on top of the COSMAC VIP to make game programming easier). But a few months ago I got really interested in embedded software, so decided it would be neat to port my emulator to a STM32 MCU and design a console around it as a learning experience, since CHIP-8 never existed as a physical system. I didn't know much about embedded software when I began, and even less about electronics, but I managed to…

In the wake of all the Unity nonsense, just wanted to toss the Raverie engine into this mix :) We’re building off a previous engine that we worked on for DigiPen Institute of Technology called the Zero Engine with a similar component based design architecture to Unity. Our engine had a unique feature called Spaces: separate worlds/levels that you can instantiate and run at the same time, which became super useful for creating UI overlays using only game objects, running multiple simulations, etc. The lighting and rendering engine is scriptable, and the default deferred rendering…

I’ve been working on this for about a year through four major rewrites. Godogen is a pipeline that takes a text prompt, designs the architecture, generates 2D/3D assets, writes the GDScript, and tests it visually. The output is a complete, playable Godot 4 project. Getting LLMs to reliably generate functional games required solving three specific engineering bottlenecks: 1. The Training Data Scarcity: LLMs barely know GDScript. It has ~850 classes and a Python-like syntax that will happily let a model hallucinate Python idioms that fail to compile. To fix this, I built a custom…

I've been spending a lot of my spare time over the last year creating this little racing game. It's built in PICO-8, which is a really fun “fantasy retro console” that's been mentioned on HN several times. The console has strict limits and I wanted to see how far I could push them The source code for the game is over here: https://github.com/maxbize/PICO-8/tree/master/Driftmania. It's a bit of a mess, but I'm happy to answer any questions on it or development of the game. Cheers! EDIT: For those not familiar with PICO-8, there's only a few inputs: arrow…

As part of the annual JS13K games challenge, I've put together a pretty large (but small-in-code) Metroidvania game that fits in just 13KB of compressed Javascript. The source is available here: https://github.com/arikwex/infernal-sigil NOTE: the current head of the main branch is at 13.6KB due to quality of life patches. The legit 13KB version is tagged in github. Useful hacks: - Using Roadroller (https://github.com/lifthrasiir/roadroller) for compression - Compressing the map data as grayscale PNG paired with some code generation. - Using procedural…
