Jump and diagonally spark up left to land on the upper platform. The Powamps can be used as a reference of when to spark, however they move up and down. Spark when samus is a few tiles left of the first Powamp, or almost half way between the first two with HiJump.

Requires:

"h_storedSpark",
{"or": [
  {"shinespark": {"frames": 34, "excessFrames": 5}},
  {"and": [
    "HiJump",
    {"shinespark": {"frames": 31, "excessFrames": 5}}
  ]}
]}

Dev note: Because this jump is somewhat blind, the excess frames are not very tight.
