I need a GBA utility dev who can make a texteditor

Hi. I am new here! I make Gameboy and Advance projects with my first one for translating! To start off, I need a Japanese expert who can read the language better than Google and someone who knows how to program a simple to use text editor like the ones used for Pokemon and Fire Emblem games. I am trying to translate 2 lesser known RPGs not many know about. a friend on Discord told me about this game and I seem to be the only one interested to come up with a English patch soon! Theres currently no English patch for these 2 games yet and that is what I am trying to work on. Let me know if you can help!
