I've used a registry editor on Linux before to pull the Bluetooth pairing keys off my Windows partition so I could add them to my Linux Bluetooth config so the Bluetooth device would work on both systems.

Editing *.regs to be used in either your Windows partitions/VMs or Wine prefixes.

I used a win2k reg editor in wine years back to do nondestructive forensics on a windows partition.

Fix/hack Windows boxes.

If you use Windows, you can install that software to browse your registry. If you have already set up Flatpak via WSL or whatever, I can imagine that being a decent option.

I guess for WINE and Proton maybe.

I've had to modify disc assignments on my Windows install to get it to boot properly, having a registry editor in Linux would have been so convenient.

I can also see some use cases for using it to modify Wine prefixes rather than regedit.

Trying to edit offline registries in WinRE is a pain in the ass, assuming this does that it'd be a godsend

I've only ever used regedit (on a linux distro) with wine tricks to try to get script mods to work for games. I think it was GTA, and skse and I don't think it fixed my issue I was just blindly following whatever I read on reddit might make it work. I'm so glad proton has matured it used to take me a couple days to figure out how to get one game to run on Linux. I hated setting up prefixes, and messing with winetricks when I barely knew what I needed.

I didn't look at the page but others are saying that might be the usecase and that checks out with me.

If you're on bazzite maybe this is a way for you to get access to tools on a immutable system? Though I think on bazzite you would just use steam tinkers launcher to access wine/proton tricks no? Its a flatpack so should be on discover store, and you can't install winetricks through CLI.

Sadly fails to launch on my machine
