Hack Suite

This hack suite is written in Kotlin (because GUIs and portability). It has tools to edit Palettes, Dialogue, Sprites, and more. Do note that it is a WIP, and not all the features are implemented yet.


If you find any new research on SB, make an issue and we can discuss expanding upon it or including it into the Hack Suite. Stand-alone tools can also be placed in this repo, just submit a PR and make sure your code is documented and pretty.
