Right.  This was already asked about in another thread.  Kirua had said in that thread that the wrong warp had yet to be properly tested on an NES Classic.  See, platforms such as VC work differently than the original NES version does - you simply can't do the wrong warp on VC or Bizhawk, as I recall, because their coding works differently than the original NES, so even if your setup is perfect, you still won't get the wrong warp.  So it's very possible that, as with the previous examples, the wrong warp simply doesn't work on the mini.  I haven't heard of any of the board's higher-ups thoroughly testing it, however, so I don't know anything definitive - I'd say it'd be best if Kirua, Tompa, or someone similar came in and gave a better explanation and/or tested the wrong-warp so you could be provided a more concise and accurate answer.
