Entrance condition:

{
  "comeInWithSpark": {
    "position": "top"
  }
}

Requires:

{
  "heatFrames": 79
}
{
  "or": [
    {
      "and": [
        {
          "shinespark": {
            "frames": 79,
            "excessFrames": 5
          }
        },
        {
          "heatFrames": 105
        }
      ]
    },
    {
      "and": [
        {
          "shinespark": {
            "frames": 79,
            "excessFrames": 15
          }
        },
        {
          "heatFrames": 165
        }
      ]
    }
  ]
}

Unlocks doors:

{"types":["missiles"],"requires":[{"heatFrames":50}]}
{"types":["super"],"requires":[]}
{"types":["powerbomb"],"requires":[{"heatFrames":110}]}

Dev note: 5 excess frames is the maximum for which it is still be possible to reach the door without running out of energy, in the case where the shinespark ends at 29 energy and Samus has no heat protection (or reserves to refill from). The alternative with 15 excess frames is mainly useful in the heat-proof case.
