I've released the first alpha version of kobopatch (the all-in-one version). The instructions for testing it out are in the GitHub release: https://github.com/geek1011/kobopatc...ses/tag/v0.4.0
Please try it and tell me what you think.
BTW, I'm working on a backwards-compatible shorthand version for the patches to make it less tedious to write the byte arrays.
