ROM Hack Kaitou Rousseau Translation Question

[feiyuncxd]

I want to translate nds game Kaitou Rousseau. The tutorial and system text have been found, but the main story dialogue texts have not been found. I saw a post before, which may be in arm9.bin file, and it is compressed. If anyone has studied the game and how to decrypt the file, I hope you can help me to solve it,thanks!

Have not taken a look but if you have encodings for other parts it is reasonably common for them to share, or otherwise be in known format.

Compressed ARM9 is no problem. Crystaltile2 (click on the little ds icon, find the arm9, right click and there should be an option to decompress) and the blz part of https://www.romhacking.net/utilities/826/ should both be able to handle that.

Making more than small edits to the ARM9 is a pain as you will run into pointer issues very soon on and they are more annoying than the file level ones most other games deal with. They will tend to be memory based so you get to figure out where it sits in RAM (a memory viewer will tell you, as will tools like ndsts or anything that can properly analyse a DS ROM) and also whether you have any extra space you can use (this is the really hard part, I normally see if there are wifi error messages to overwrite but that only gets you so far).
