Yeah, you can use sky3ds on latest firmware, but its just a game cart emulator, doesn't even have a software menu, only gateway (A cfw that uses a flashcard as a key to use it and can run 3ds roms from it) and cfw need below 9.2 firmware for a kernel exploit, but i really want a kernel exploit because i opened my 9.2 3ds that was updated to 9.9 by accident, and wrecked it after hardmodding it to restore 9.2 nand, if there was a kernel exploit then my 3ds wont be broken because i could of just use a software based nand flasher
