I dumped my Y and OR cartridges with the GW launcher and decrypted them with rxTools. With PackHack, I've extracted everything from the exefs and the romfs, I have the banner.bin in exefs. X/Y and OR/AS are supposed to be region-free, and they contain all the data for the different languages and it will show a different banner and header info depending on the language your 3DS is set to. I'm trying to edit my rom so I can repack it as a .cia and install it on my rxTools emunand, but have it show the Japanese banners instead of the English banners even though my emunand is in english. Is there a way to do that? If the banner.bin contains the banners for every language, there should be a way to swap out the English and the Japanese ones, no? I was able to extract the banner data from banner.bin, but 3DSExplorer only shows this: Maybe the format isn't completely understood yet?
