So... this one just came out. But it looks like it does not boot on any CFW. However, it will on Gateway's launcher and emunand as .3DS and .cia. Something was said about a new type of crypto usable on old 3DS post 12 here https://gbatemp.net/threads/download-seedconv-seeddb-bin-generator-for-use-with-decrypt9.392856/ did Gateway patch the 9.6 keyslot already? Something else maybe?
