This game is server sided, unfortunately. Whenever you’re playing a game where you’re competing with real people, it’s impossible to hack.
KKH for example, it’s mostly story/single player based, but the SYS events, which require tickets and reward diamonds, is server sided. Meaning, the tickets that you need to submit a look can’t be modded, same with the diamonds. I tried modding the tickets with a cheat engine and it changed the numbers but as soon as I submitted a look, the number changed back to where it was minus one.
Edit: I’m on the 13 pro max lol idk why it says 8+
