Have you ever wanted to remove the truck animation from the start of Pokémon Sapphire without any adverse effects? Or maybe you wanted to edit the positions of the player on their starting map instead of them always starting out in the middle? Well then, this is the patch for you!

To edit the starting map, X position, and Y position, go into a hex editor at these offsets:
0x52E10 for the map bank
0x52E12 for the map number
0x52E14 for the starting X position
0x52E0C for the starting Y position
