this has been mentioned to death many times and that's how the code works.
for pete's sake, use the search button and learn how to read before demanding things left and right here.
yes, the shiny code works even underground.
you just have to hold the button to trigger shiny before entering the cave and all the pokemon inside said cave will be shiny.
Yes, this works for me too.
Pressing L just after the pokemon photo show up and you have the option to choose "yes or no", then while pressing L select "yes".
Your starter pokemon will be shiny.
