Oh, I didn't have anything specific I wanted to delete. I was just curious if your hard delete method could be used to delete demo mode or something. My thought was to free up some space. Unless someone could walk me through it I wouldn't know how to start anyhow.
Theoretically it can be used to delete something pre-installed you don't want to have.
But I don't know whether those files you want to delete link to any other file or not.
If they did link to any other file, then delete them may cause unknown error.
Personally I only use that method to import/delete DOSBOX games
- Hakchi only load .exe files to temporary working directory but to properly run the .exe files it requires loading all the other non-exe files to temporary working directory either.
That's why I should manually import files into NES mini.
And I just thought the files you want to delete was the same as what I imported - they can't be properly removed by mounting game or deleting via Hakchi, which occupies the NAND space.
But to be noticed that if the file you want to delete is a system file, please use linux command to backup it before deleting.
For the error happened after an interruption, you can try reflashing custom kernel.
