Been working on a little side project since a while: a player for HSC files, the AdLib/OPL2 tracker format from HSC-Tracker and NEO Software’s early-90s DOS games.

Some things I’m happy with:

It sounds like the original. Instead of porting another player, I disassembled the original HSC-Tracker 1.5 replay routine and rebuilt it in Lua. I checked it against the original code running in an emulator (and the real TSR in DOSBox): same register writes on every tick, for all 63 tunes from the tracker package.

Real FM chip emulation via Nuked-OPL3 through LuaJIT FFI. If the DLL isn’t there, it falls back to a pure-Lua OPL2 emulation, which turned out way closer to the real chip than I expected.

The UI is drawn 1:1 on a 640x400 canvas with an 8x8 BIOS-style font and the 16-color VGA palette, plus raster bars, a scope, a spectrum analyzer, VU meters and a sine scroller, because of course.

File browser: you can open any folder on disk, or just drag a folder or .hsc file onto the window.

It comes with a small original demo tune, since the classic HSC tunes can’t be redistributed.

Code’s here if you want to poke around: https://github.com/SiENcE/love2d-hsc-player

If anyone still has old HSC files lying around, try it!

• it's the included Sample from GB Studio 4.3.2
• all 17 scenes working
• music + sfx fully working (not here as this is a gif)
• colors are only ~90% equally just because it's a GBC conversion
• minor issues wit Space Scene

It's a Testcase for a much larger mission.

Cast spells, not tweets. SpellCast is a X | Twitter-like social app with no servers, no accounts, and no company in the middle. Your messages (called "spells") travel directly between you and the people you connect with, and everything lives in your own browser. It's a single web page - nothing to install.

Hi,

I’ve been working on a small open-source project called - aar:

https://fischerf.github.io/aar/

It’s an AI coding agent/framework in Python, but the main point is that it stays pretty small and readable.

A lot of tools in this space are impressive, but also quite opaque. I wanted something that can do the usual agent things — CLI, TUI, ACP editor integration, tool use, sessions, web/API mode, provider switching, sandboxing — while still being understandable enough that you can open the code and actually follow what’s going on.

A few things that may be interesting:
- thin core loop
- Python 3.11+
- open source / Apache 2.0
- works with Anthropic, OpenAI, Gemini, Ollama, and OpenAI-compatible endpoints
- terminal UI + full-screen TUI
- ACP support for editor integration
- sandboxed tool execution / safety features
- persistent sessions across providers switches
- typed event model
- queued prompts
- shadow branching (session-scoped git isolation)
- extension system

So I guess the pitch is:

If you like tools like Claude Code / Codex, but want something more hackable in Python, local-first, and easier to inspect, this might be useful.

If you try it and have ideas, I’d be glad to hear them.
