Alright, spent the better part of the evening updating Sakura Suite and my plugin for it to the latest version of Athena, as well as migrating it to cmake, for those of you who are impatient: VS2015 minimum, make sure to clone both ......
After that simply compile both Sakura Suite and SkywardSwordPlugin, and when you're done place it in a directory called "plugins" next to the SakuraSuite executable. From there you should be able to edit saves.
EDIT:
If ANY of you wish to contribute, please feel free to fork and make PRs, I'm not above taking external help when it's provide, in fact I welcome it. Also, despite the source claiming to be GPLv3 it's actually MIT, I just haven't gotten around to changing the licenses out yet (that's next on my list)
