This is the page for the project OPN64, formerly known as OPN-462.

This project hasn’t existed for a number of years and I no longer take support requests for it. This project would be something I’d need to completely rewrite in order to  account for the plethora of new possibilities in the OPN codes which didn’t exist at the time. For this reason, it’d be a massive undertaking and I don’t have the kind of time for a project of this size.

That isn’t to say that it won’t exist again sometime in the future 🙂

Best regards,

Terry Butler
