How would you do that?
1. Dump your game as an nsp (or even the raw files)
2. Use one of the programs from this site to extract the contents of the dump
3. Download this pack
4. Use the pack's contents to overwrite the files of your game dump
5. Repack the game dump with the patched files as an nsp
6. Install the newly made nsp.
But keep in mind that if a new update comes that overwrites one of the patched files, you'll have to start all over again.
