Useful Pointers

[Charon]

This is for any useful pointers for hacking.

PLEASE NOTE: In this thread, you MUST remember to include the area of the ROM/RAM ect. you are referring to. For example, 0x8600000 is DIFFERENT from 0x600000. This way, these pointers can be used to extract numbers from memory via an ASM routine. Also, if the pointer applies to a particular game, please note that. If not, please write "GENERIC" to signify it applies to any GBA title.

Today, I only have one, but it is very useful.

GENERIC:
0x4000130 - Button press. These two bytes change whenever a certain button (or a group of buttons) is being pressed. Can be used for button-press scripts (which have different effects when you use different buttons).
