There's nothing that stops the roms from being dumped decrypted, but then they're not a copy of the original rom are they? Tools are available to decrypt the rom afterwards, and plenty of emulators will run those programs (easy way to test homebrew). It also ensures that the roms haven't been modified, as private keys are still private. That's where the group that validates rom dumps gets their name from: No-Intro. Because old rom dumps used to modify the rom to add an intro advertising whoever cracked or dumped the rom. https://en.wikipedia.org/wiki/Crack_intro https://en.wikipedia.org/wiki/Crack_intro
