While it is still not fully functional yet (everything works, but I'm missing/broken the functionality in the permutation fitter UI), I'm working on the DRM currently, so repair shops can't just use the build I upload here.
I'm not sure how long the DRM will take to build, but considering that I'm ill and starving, don't expect it in a few months.
If you want to make this homebrew from scratch then I'll be more than happy to assist with that, but my code will not come out until the DRM is ready.
