Historical QB64 versions

In the interests of preserving history, we've made an attempt to collect older versions of QB64. We admit that the collection is patchwork; sometimes we only have the compiler .bas source, and many versions are missing entirely. If you do have a version not listed here, we would be most grateful if you could contact us at contact@qb64.org.

Thanks to Daniel Roussel, CodeHunter, Stanley Adams and Michael L. Phillips for providing some of these. --- Transition from using SDL to using OpenGL ---
