I have a strange issue, edizon overlay works the first time and I can turn cheats on but trying to open it a second time crashes my Switch. Happens every time in handheld and docked. I have all the latest versions from impeeza's post.
Can't exactly remember how to use them, I also haven't played my 3ds in ages. I mainly use luma cheats though cos they're easier and less prone to crashing.
Can't remember, it's quite complicated but I found this on my 3ds. It's a plg for NTRCFW. Or you can copy the codes from this section into a text file for luma (it says 1.2 but they work for 1.3 as well)
They're referring to Switch Custom Themes using NXThemesInstaller, the best thing to do before updating is to delete the '0100000000001000' folder from 'atmosphere/contents/' to make sure you don't get a crash on boot then reinstall the theme after updating
Panda Batch File Renamer is good and free. It'd probably be fine renaming them on the sd card but you could copy them to your PC if you're worried about corruption.
