Possible codes we might want to have:

Max Samurai Skill Points
Max Ninjutsu Skill Points
Max Onmyo Magic Skill Points

Edit max storage count of 2000.
Edit max inventory count of 500.

Code for Divine Fragments (9999) doesn't seem to work for me. If you can tell me what digits I need to edit in order to find one that works, let me know.

I will then do that and share my result.
