Version Differences: Geothermal Core

Notes:

The stalagmite used in the primary method of getting the Plasma Beam early does not exist in the Japanese version of the game (as shown above).
The metal ring running around the outside of the room was made unmountable in the Japanese and European versions of the game. Also, Bendezium was added in front of the door to Plasma Processing in those versions. This also changes the Skipping the Grapple Beam and Spider Ball: Geothermal Core method slightly.
The North American Player's Choice version of the game includes a lock (shown below) placed on the door to Plasma Processing (where you pick up the Plasma Beam), which goes away when you collect the Grapple Beam.
