Can someone explain what "Step" does?(under the breakpoint tab)
buhmp
Lets the next line of assembly run, then pauses the game again.
what pizzaboy said, its useful also for debugging you're own asm codes, as well as understanding HOW something is being manipulated without remembering which register has what value etc because it shows you. So for example you write you're asm code and inject it, set breakpoint and then step step step to see if it does what you wanted it to do, and if it doesn't you can find the error. That is how it works in PC so i'd assume its the same story here.
