How to Start Translating Project on GBA Rom ?

[Whiteshadow25]

I have studied about binary and hexadecimal numbers, the document for newbies only explains how to convert and so on, but I don't know where to start editing on the hex editor to translate languages (JP to ENG) or are there other tools that I don't know yet. please guide and hint or can you help me to start this project.
the plan for the rom that I want to translate is
1. granbo (game like pokemon with unique mechanics)
2. Tomato adventure (turn based battle game with puzzle elements like tomba)
3. Magical vacation (rpg alike game that might be fun)

You can try searching for text that you know appears in the game, though you would probably first need to know the encoding, maybe by looking at how the font graphics file is ordered. If there's no support for Latin characters you'll need to add them to the font too.
