I was wondering how to edit resources to a point where you can't see the numeral, and they're unlimited. Any answers?

I think when it gets above like a million you no longer see the minerals, it's just a high number that does it.

I don't know about resources, but the leaderboard can only display 59 pixels. All numbers are 7 pixels except for 1, which is 5 pixels. To edit resources this high, use an editor like scmdraft, which will allow you to type in the maximum (4 bytes) into any numerical field like resources. 2^31-1 is the most you'll be able to put in the value (any higher results in a negative number). Therefore, those resources aren't actually unlimited, but considering 2^31-1 is a huge number, you won't run out of money any time soon.

Does the leaderboard display numbers as signed or unsigned?

signed. the negative is 5 px i think
