The planned Steam release for the emulator Dolphin was ‘indefinitely postponed’ on May 27, as announced by the creators, stating that “Nintendo issued a cease and desist citing the DMCA against Dolphin’s Steam page.” resulting in the page being removed immediately.
With emulation being a gray area in terms of legality, Dolphin makes use of the Wii Common Key in the emulator, meaning it's actively bypassing piracy protection measures.
