CRT has been developed in Visual Studio Community 2026. Where the old Commodore project was primarily self-developed, then this new Classic codebase has been developed primarily with GitHub Copilot, which is why I see myself more as a conductor for this project, rather than the pure developer of this application - all credits to the people behind these LLM models 😁

As of March-2026 I have primarily used the Gemini 3.1 Pro model, but also Claude Sonnet 4.6 and in some cases GPT-5.3-Codex (these models will of course change for the future).

As of August-2026 I have setup Claude Code (agent), and is primarily using Sonnet 5 and Opus 5.
