Thread: Next step for movement speed hack?

I spend all day, read many forum and now i can do just only Zoom hack and find base address (I'm totally newbie here T-T)

The problem for now is -> I can find the base address of my character movement speed, create them to pointer and what's next?
I try to change the value many times and the game always crash to login page

PS. Please excuse my poor English , Thank you >.<
