Help editing sprites that "contain" text in Platinum

[Martellfort]

Hello everyone, after hours of searching I found this site and I hope that someone could help me.

I want to translate the pkmn platinum game to my language, and I think I have the right tools to edit all of the text based translations of the game (SDSME and DSPRE). I have even managed to edit the cover image (Tinke). But... My problem is with the text that integrated in sprites, such as the bag menu, that shows the word "Bag" and "pocket". I tried to do the same as with the cover image, but the bag unpacked "folder" is very much complicated in comparison with the title one, and the result was a big pixel mess when I extracted, edited and reimported the png file, and opened the edited game and opened the bag.

Is there any easy way to modify this sprites? Now I identified the bag menu, but I suppose that there are other ones with text in them, but I expect them to be editable like the bag sprite, in the case that I learn how to do it.

I understand that the majority of tutorials/tools are oriented to edit pokemon sprites, but is there any option to edit those other sprites too?

All help will be much appreciated.

Thank you very much in advance.
