It's completely understandable that this would be shelved. If it's for a game you no longer play, why would you continue to develop it? That makes sense.
Is there any possibility of getting it open-sourced to github? If not, that's understandable too. It just means starting from scratch with no template to work from.
I do want to say thank you for creating the RTST in the first place. It was great while it lasted.
