Upgrading the Additional File Formats Tool

I’ve made a couple of attempts to reach the original author of the Additional File Formats tool to find out if it would be okay to attempt upgrading this to work with Renoise 3.1, but haven’t gotten any sort of response.

As I’m a complete noob to Lua, I was wondering if anyone could explain to me what it is about this tool that makes it incompatible with the latest version of Renoise: Is it just that things in the API were renamed? Is there any reason this tool can’t be updated to be used in the latest version of Renoise?

This was a great tool, and it’s a shame that it only runs in older versions of Renoise.
