Albert, look in your new \doc folder, there's a PDF in there that looks like an instruction manual for a built-in FM loader. I haven't tried that yet, or Darkloader, I only just now got T2 working and managed to play through Interference for a few minutes. Now that's working, I'm going to try out the new editor.
Edit: Looks like you found that doc. As folks figure out how to use it, I'm sure they'll help out.
