System 2 is the "Battle Menu Set", used in battles to determine the cursor for targeting enemies and allies. It also displays the ATB bar and the numbers for HP and MP display in gauge type battles (set in the Battle Layout options of the Database).
Gold System Set 2
A gold themed System Set 2 reminiscent of royalty, this was the first I ever created (or re-created would be more accurate). The numbers on the gauge aren’t really that clear, but I kept it as is for posterity.
