• For example, the Yuzu emulator, a key ancestor of sudachi, was subject to legal settlement, and official development was discontinued.
• Software that mimics hardware, or emulators, are not generally illegal.
  What becomes illegal is distributing copyrighted game ROMs, firmware, or encryption keys without authorization.
