ROM Hack Pokemon XY/ORAS keyboard translation problem

[Slashkin]

Hello! I have a situation here. We try to translate Pokemon X/Y and ORAS to our native language. And we stuck at keyboard translation. I want to replace Latin letters with Cyrillic, and it seems to me that everything is hidden in the СRO files. I don't know how to open them or edit. Can anyone help me please? Or explain where to look this information.
Sorry for any spelling mistakes, English is not my native language)
