Hey Aminoacow,
I hope you did not abandon this project, and still around, because my understanding is that this editor was made for a more accessible tool than the CE I guess, if not better considering its current state.
Thank you and all the people for the efforts credited for in the OP.
I initially somehow ended up downloading this zip below and couldn't figure it out what it was for and still:
https://github.com/tmxkn1/D-OS-Save-Editor/tree/v1.6.0But only then I figured it out that I should have just downloaded the alpha.preview.v1.6.zip.
I'm looking forward to hearing from you.
