Hmm...after using GARBro (Game Resource Browser) to browse the scripts.bin you provided...ah this is the script from "Tincle ★ Twinkle Festival!" I see!
Very nice! Are you planning on translating it or just trying to read the scripts for eaiser time to play? Either way let me help!
In GARBro, It says that the scripts.bin is a DxLib Engine Resource Archive (Though the game was made in Pix Studio so I guess it uses DXLib which is Interesting!).
I don't know anything about DxLib but I believe they're tools to archive it, GARBro is able to extract the scripts.bin so if you want that you can get it here:
https://github.com/crskycode/GARbro
(I'm using a forked version of GARBro as this is more active and up-to-date)
Extract and Open GARBro once done, then either open or browse to the folder where your scripts.bin is and you can either open it to browse the script files or choose to extract it!
(When extracting, make sure to tick off "Extract Images" and "Extract Audio" as they're no such files within the scripts.bin and it'll not properly extract them!)
As for archiving the scripts back together well...I saw a tool called "DxaEncode" but I don't know if it's the right program to do it or if there's something better/different needed to archive it, give it a try though as you can find instructions and the DL link under "DXLibary" here:

Hope this helps, your welcome and see ya!
