I, like many of you, have purchased a Japanese 3ds and installed CFW.
After installing a few USA CIAs I've noticed that some titles show their banner in Japanese, although the game does play in English.
Examples of this are Ocarina of Time, Majora's Mask, and a few Pokemon titles.

What is the current method for changing these banners to English?
To be clear, I do not want to region change the entire 3DS, just the animated banner on the top screen when selecting the game.

Thanks for your help!

Small out-of-region banner fixing guide.

We are interested in .bcmdl files, it is different for each region and language. Here is the list:

  • banner1.bcmdl - EUR_EN
  • banner2.bcmdl - EUR_FR
  • banner3.bcmdl - EUR_GE
  • banner4.bcmdl - EUR_IT
  • banner5.bcmdl - EUR_SP
  • banner6.bcmdl - EUR_DU
  • banner7.bcmdl - EUR_PO
  • banner8.bcmdl - EUR_RU
  • banner9.bcmdl - JPN_JP
  • banner10.bcmdl - USA_EN
  • banner11.bcmdl - USA_FR
  • banner12.bcmdl - USA_SP
  • banner13.bcmdl - USA_PO
  • banner14.bcmdl - CHN_CN
  • banner15.bcmdl - KOR_KR
  • banner16.bcmdl - TWN_TW


Now what to do whit it:
  • Create a copy of game .bcmdl file from another region. Select one that is displayed correctly on home screen. I think the best bet here is banner from native region for your game.
  • Rename this copy to region you need (list of names-regions is above).
  • Open your .bcmdl file in hex editor and go to 000011D0. We are interested in the selected text (in this case, JPN_JP). Change it, for example, to EUR_RU. Save changes.

So after a few hours of digging I found this guide to follow.
Could someone help me understand exactly what files in which folders are to be edited and put where?
I have a JPN 3DS and USA CIAs so the banners are displaying in Japanese but I would like them in English.
I can't seem to make sense of any of the extracted files in Hex Editor.
