Most of the app is standard AppKit code I wrote by hand, but the low-level rendering stuff was a complete blind spot for me. Using AI to bridge that gap allowed me to move beyond a simple MAME frontend and actually implement something with better performance on macOS.\n\nFor anyone curious about the technical split in this project:\n\n**Manual Code:** The entire native macOS UI and the tedious process of ROM compatibility testing.**AI-Assisted:** The website and the integration of libGeoLith/Metal. Without an LLM, I would've been stuck in documentation hell trying to figure out the rendering pipeline.\n\nThe app currently lets you toggle between the GeoLith core or a self-managed MAME installation. It's basically designed for people who want an OpenEmu-style experience but specifically for SNK classics like Metal Slug or Art of Fighting.\n\nIf you're looking for a practical tutorial on how to integrate C++ libraries into a Swift/AppKit project using AI, this is a great real-world example of using an LLM agent to handle the \"scary\" math and graphics code while the human handles the architecture and UX.\n\n`https://apps.apple.com/us/app/neobox-neo-geo-player/id6769912877`\n\n[Next Unlayer: A Complete Guide to Embeddable Builders →](/en/threads/2297/)\n\n## All Replies （3）\n\nA\n\nD\n\nF\n\nClaude's actually been a lifesaver for my Swift projects lately, saves so much boilerplate.\n\n0", "url": "https://wpnews.pro/news/neobox-building-a-macos-neogeo-frontend-with-ai", "canonical_source": "https://promptcube3.com/en/threads/2312/", "published_at": "2026-07-23 13:00:49+00:00", "updated_at": "2026-07-23 21:08:54.711785+00:00", "lang": "en", "topics": ["developer-tools", "artificial-intelligence"], "entities": ["NeoBox", "Claude", "libGeoLith", "Metal", "MAME", "SNK", "Metal Slug", "Art of Fighting"], "alternates": {"html": "https://wpnews.pro/news/neobox-building-a-macos-neogeo-frontend-with-ai", "markdown": "https://wpnews.pro/news/neobox-building-a-macos-neogeo-frontend-with-ai.md", "text": "https://wpnews.pro/news/neobox-building-a-macos-neogeo-frontend-with-ai.txt", "jsonld": "https://wpnews.pro/news/neobox-building-a-macos-neogeo-frontend-with-ai.jsonld"}}
