I am currently using a japanese new2dsXL, and I decided to keep it JP for the online connectivity. I was looking into home menu patching, and have tried using the HomeMenu tool by @Asia81 . I replaced the "RomFS\message\JP_Japanese\menu_msbt_LZ.bin" with the english one, re-packed, installed the CIA, and got a crash. Next I tried decompressing the menu_msbt_LZ.bin, as well as the english one, and copied over all the entries, saved, re-compressed, re-packed, installed, still got a crash. I tried LayeredFS in Luma 8.1.1 for a safer approach, although that appeared to not load the patch (I put it in luma/titles/0004003000008202/romfs/message/JP_Japanese/menu_msbt_LZ.bin). I've seen a video of this being done before, so is there any insight to getting this to work? Bonus points if I can get the system settings to translate too. In a nutshell, I'm trying to make my 2DSxl as english as possible without actually region changing it.
