To my understanding CFW atmosphere protects against e-fuses getting blown and the cartridge slot getting updated past the firmware level on the actual NAND. Does it protect against overvolting components on the motherboard? I know there were Pokemon Let's Go games containing malware which overwrote the NAND. Does using emuNAND and backing up your SD card before running a new game protect against this? What is the worst that can happen? Is it worth the risk?
