This will help you determine where in memory you can find the registers for a given window.
Steps:

  1. Input the window number you are interested in (ex. window 1 is the main text window, window 14 is main battle window)
  2. Press enter
  3. Go to the address of the existence table entry in the emulator's memory viewer, and record the value there (0-7)
  4. Enter the value from the existence table into the "Window Stats Index" input
  5. Press enter
  6. The address of the window registers should be populated

Current Window:

Address of existence table entry: $XXXXXX

At that address, you will find the index to the window stats table for this window.

Window Stats Index:

Address of window stat struct: $XXXXXX

Address of window registers: $XXXXXX
