[VXA Script] Select Key Item ACE

Code:
# * Select Key Item ACE * #

#  Scripter : Kyonides Arkanthes

#  2024-03-22



# Display your Key Items on screen with style!

# Don't forget to add some key items to your party's bag before calling

# the Select Item event command or this script might laugh at you! :O

# You might only need to configure 5 CONSTANTS, yes in ALL_CAPS.

# Yet, this script can run just like any plug & play code available out there.
