Hi everyone, among all these Pokemon Sun and Moon hype, and from what I've researched so far, this could be an unpopular request, but I think I have reached my wit's end and need your help. What I am after Changing the 3DS logo/animation when booting an app/game What I have been able to find out is the Logo region is responsible for this (https://github.com/ihaveamac/3DS-rom-tools/wiki/Glossary) . For new games, they are not included in ROMFS or EXEFS. What I have been able to do so far So far, I have been able to use various guides to extract the contents of all NCCH regions from a CIA. The Logo region can also be extracted and in a BIN format. I can use EveryFileExplorer to open this BIN file and find out that it contains a few different files in various format, including BCLIM. EFE allows you to export/import between BCLIM and PNG, so the format is not a problem. However, I need a way to unpack this BIN file (similar to a ZIP file), change the file and repack into a BIN file, so I can ultimately repack it into a CIA. Reason why I want to do this I want to customise this is so that when a game is booted up, a little reminder can be shown for my children to see. I think for people who likes to edit ROM, they can have a little personal touch to show too when their game is booted up. I know they can edit various texutures and files in the main ROMFS to show these things in-game, but the ealier reminder wouldn't hurt. Thank you for reading. TL;DR Please, anyone knows how to open up the Logo.bin file from NCCH and rebuild them? Thank you.
