Walk to the middle of the cave and use flash.
to catch the Regis, you first have to complete the underwater cavern somewhere around sootopolis. it REALLY helps if you can interpret braille. after that, to get to registeel's cave, which is south of fortree, on a side path, then follow the braille instructions in that cave. then a passage should open to registeel.
A braille reader does not exist in Pokemon Ruby or any Pokemon game with braille used as a puzzle. Translating the braille for yourself is very simple if you print off a braille alphabet sheet.
You can only get registeel in ruby and sapphire and emerald.
Registeel is unobtainable from Pokemon Diamond and Pearl. You have to migrate it from Pokemon Ruby, Sapphire, or Emerald.
Registeel is not catch able in Pokemon LeafGreen. In order to get a Registeel you will need to trade for one from Pokemon Ruby or Sapphire.
You can't find Registeel in Pokemon Platnium. You just migrate it in Pokemon Ruby, Pokemon Sapphire, and Pokemon Emerald.

You cannot catch Registeel in Pokemon LeafGreen. This is due to FireRed and LeafGreen being able to trade with Ruby and Sapphire. Pokemon Ruby and Sapphire have the three legendary golem Pokemon including Registeel.
Trade it from ruby, sapphire or emerald.
