A question.

[A-Man]

For those who want to know why.
I had a large sprite sheet, and I wanted to split it. I did split it but the problem is that the sprite sheet contains sprites used in multiple dat files. And they are at the middle of the sprites directory list in the dat files. and I don't want to miss with any sprite number below the split one.
so,

is it ok to write a file(x-x),col: x number which is higher than the real one in order to prevent usin' a fake sprite (imaginary sprite) to fill the missing/blank sprites numbers? I know it works but will it take the same memory as if it is the large sprite?

Any help appreciated....
