I bought the controller adapter to use it with Project64. The adapter and controller are recognized immediately. In most games, the controller works (all original and hardly worn!) For example Mario Kart racing or Diddykong properly, but for example, in Super Mario 64, Donkey Kong or Zelda (all tracks), the characters often sneak. By fine-tuning, it is possible to improve this, but it is possible not to always run fast.
For from time to time to test or play a game before you get it At length the adapter for the console to good use.
