   Ghidra Plays Mario▲207

   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…

   I made a programmable computer from NAND gates▲420

   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.

    Finally got my hobby OS up and running on real hardware. I love the old IBM thinkpads, so thought it was the perfect machine to get it working on. Been working on it for quite some time now, but this has been a big milestone!

    Game Bub – open-source FPGA retro emulation handheld▲274

    Hey HN, Over the past ~1.5 years, I built an open-source FPGA retro emulation handheld that can play Game Boy, Game Boy Color, and Game Boy Advance cartridges. To my knowledge, there isn't an existing open-source FPGA emulator that can play physical cartridges like this. One of my main goals was to do all of the pieces myself, and be able to understand every component of it, so I designed my own PCB, wrote the firmware, wrote a Game Boy and Game Boy Advance emulator for the FPGA (using the Chisel HDL), and designed a 3D-printed case. I detailed the design and development process in the…

    I made a game where you build a CPU from logic gates▲102

    I built ChipBuilder to make computer architecture more approachable through interactive puzzles. You start with basic logic gates like AND, OR, and NOT, then gradually combine them into adders, multiplexers, memory, an ALU, and eventually a complete CPU. Once you've built the hardware, you can write assembly programs that run on the processor you created. The game is inspired by courses like Nand2Tetris, but everything runs directly in the browser with a visual circuit editor, simulations, and progressively harder challenges.

    A DOS-like hobby OS written in Rust and x86 assembly▲207

    To try it out, simply build the project yourself from source, or use attached bootable ISO image of the system (in Releases on Github) and run it in QEMU. https://blog.vxn.dev/rou2exos-rusted-edition

    A cross-platform terminal emulator written in Java▲65

    It's based on the jediterm library developed for IDEs, but it can also be put to work as a standalone terminal emulator with tabs. The library has been around for more than 10 years, but I don't think anyone made a terminal emulator app from it?

    Homegames. An open-source game platform I've been making for 8 years▲229

    I'm making a platform for simple open source games you can play anywhere. Games are all just JavaScript classes and you can read the source of every game on the platform. I started working on initial "games" (mostly rendering tests) in 2018 and eventually built all of the platform stuff around it to make it easy to share games. There's also an in-browser editor available for you to make and publish games all from the browser. Would love some feedback on the games and studio features as well as the platform overall. All of the code is available at https://github.com/homegamesio
