Introduction
Hello everbody and welcome to the Final Fantasy Tactics Advance Shop, i have recently just upgraded and messed around with it to make it look even more like the FFTA shop, there is still quiet a bit more to do but i have almost completely finished it, but to finish this completely i'm going to have to create my own skill equipment system -_-...a challenge! ^_^
Enjoy!

Script
Add above main.
Code:
#----------------------------------------------------------------------------
# Final Fantasy Tactics Advance Shop System By Mac      v. 0.7
#----------------------------------------------------------------------------
# Basically as it says in the title, this makes your shop system just like
# that of FFTA but due to being aliased you have the option at any point to
# switch it too and from the default system whenever you see fit.
#----------------------------------------------------------------------------
# Firstly to make this active in game you need to do a call script and call this:-
# $game_temp.call_fftshopsystem = true
#
# Then at any point you can call it again but with false to return it to the
# default shop system, or if you want this system to always stay on simply
# change the line:-
#
# @call_fftshopsystem = false
#
# Too:-
#
# @call_fftshopsystem = true
