I hope this is the right place to post this but I've spent the last couple days practicing my rusty French skills working on this and I've got about 99% of the current French dialog translated there's a couple cut scene dialogs and dungeon owl statues I need to do still, but everything else is done. I added the rest of the boss welcome dialogs and some npc dialogs that were not yet in the french translation where it seemed reasonable. I tried to keep to the naming convention in the project so hopefully it should be alright when they're added.
I plan on keeping it up to date along side alttd's development and if the team wants they're more than welcome to use this in the project.
I used the text from the original Link's Awakening DX where possible and for text that wasn't in the original game I tried to keep the style and tone of the original game.
To use this just add the languages folder from the repo here
https://gitlab.com/grawprog/alttd-english/to the alttd project data folder
https://gitlab.com/zeldaforce/zelda-alttdThen use the solarus editor to add the language to the project.
I hope this is helpful in some way.
