{"slug": "show-hn-lemmings-in-html-in-canvas", "title": "Show HN: Lemmings in HTML in Canvas", "summary": "A developer reimplemented the classic game Lemmings using HTML-in-canvas and a DOM-based Entity-Component-System, heavily assisted by Claude Code (Sonnet 5 High). The project adds support for EGA, CGA, Tandy, Adlib, and PC Speaker audio/video modes, enabled by hooking the AI to Ghidra MCP and DOSBox MCP. The developer notes feature creep may have introduced bugs and invites feedback.", "body_md": "For fun I decided I wanted to reimplement Lemmings using HTML-in-cavas and a DOM-based Entity-Component-System. I made heavy use of Claude Code (using only Sonnet 5 High) and I used everything already published on this topic. I used already existing HTML ports (like DHTML Lemmings, LemmingsJS and Lemmings.ts) to kickstart development.\n\nEven though I was able to add some new stuff like EGA, CGA and Tandy as well as Adlib, Tandy and PC Speaker that wasn't documented (or I didn't find it). I, or rather Sonnet, was able to do so because I hooked it up to a Ghidra MCP and a DOSBox MCP.\n\nAt some point feature creep set in so I am guessing there are still a few things not working as intended. I'd love to hear all about it.\n\nComments URL: [https://news.ycombinator.com/item?id=49057415](https://news.ycombinator.com/item?id=49057415)\n\nPoints: 1\n\n# Comments: 1", "url": "https://wpnews.pro/news/show-hn-lemmings-in-html-in-canvas", "canonical_source": "https://github.com/VorticonCmdr/lemmings", "published_at": "2026-07-26 12:23:47+00:00", "updated_at": "2026-07-26 12:52:58.817587+00:00", "lang": "en", "topics": ["developer-tools", "ai-tools"], "entities": ["Claude Code", "Sonnet 5 High", "Ghidra MCP", "DOSBox MCP", "Lemmings", "DHTML Lemmings", "LemmingsJS", "Lemmings.ts"], "alternates": {"html": "https://wpnews.pro/news/show-hn-lemmings-in-html-in-canvas", "markdown": "https://wpnews.pro/news/show-hn-lemmings-in-html-in-canvas.md", "text": "https://wpnews.pro/news/show-hn-lemmings-in-html-in-canvas.txt", "jsonld": "https://wpnews.pro/news/show-hn-lemmings-in-html-in-canvas.jsonld"}}
