Confirmed working with 6.2.0And because of no Polish language as system language many games that have Polish in other consoles don't have it in Switch release (mostly because devs don't want to add language menu in-game). For now i counted 71 games in that regard, from which 30 I accomplished to swap polish files with english.We have Switch officially in Poland, but not from Nintendo. We have it from Czech distributor.And thanks for this project. I will check it and write any errors that i found if you are not confident of your language skills.And about it:Have you tried hex editor, not Kuriimu?In which file is this text?
