So I recently looked into Hexadecimal stuff and wanted to ask: how do you know where to edit? To hold it simply let's say you wanna edit your ID Number in Pokémon. Would you just search for the ID in HxD? Will the ID be handled as a 5 digit number or is every number a single digit? I know you could just change it with PK3DS but I just want to know how it basically works. A harder example let's say you wanted to change an item in Zelda OoT3d or MM3d. How do you do this? How do you know which item has which number code and how long is it?
