I currently have 2 3ds. 1 USA OLD 3ds XL with al9h(first version) and luma(old version) sitting at firmware 10.0 the other one is a japanese new 3ds xl at 11.4. I want to ask if it's possible to do dsiwarehax with these two. If I change the region of the USA old 3ds xl to JAP, and then buy the game at jp eshop and do the system transfer to target 3ds, do you think this will work? thanks.
