| You could always start out at ground zero, by looking at existing Gameshark/Action Replay codes for the games. It's what I occasionally do in order to find relevant data for SM64 hacking. Here is a great site to start. |

Pointers on the GBA are super easy and work as such:
if your address is 123456, a pointer to that address would be the bytes reversed with 08 on the end of it. An address of 12 34 56 would have a pointer being read as 56 34 12 08, in this case. If no pointer is being found, you might not actually have the right starting address, maybe you're off by a few bytes? Keep playing around with it and I'm sure you'll be able to figure it out eventually repointing GBA data is one of the easiest things ever I've found. Could you possibly be more specific with what you are doing? |

Repointing graphics locations is pretty easy, though if it would fit 1:1 you may just be better off physically replacing his graphics in the rom with a tile editor or the such. if it's compressed, UNLZGBA is a program that works pretty well for editing compressed graphics  |
