Description
There are quite a few scripts that serve a similar purpose to this one, but to my knowledge this is the only one that does this specifically: gives each item, weapon or armor it's own possession cap, that is displayed in shop, equip and item screens. You can also set (and change in-game) the maximum amount of gold attainable. You can also now set certain items to not have their cap drawn in the windows.
Features
- Notebox tag for setting individual item caps on each item
- Notebox tag for not drawing the item's cap in windows
- Altering limit on gold, also changeable in-game
- Displays item cap in item (battle), equip and shop scenes
- You can set which types of items (items, weapons and armors) have their cap displayed in the inventory scenes
Instructions

# Item Cap - Pacman (29/12/2011)
# Version 2.3
# Written for rgangsta (http://www.omega-dev.net/forums/showthread.php?tid=1280)
# Suggestion by Scalinger2
# Use the tag <item cap: x> to set the cap of an item to number x.
# Use the tax \EXEMPT_CAP to make the windows not draw the cap at all in the
# item and shop scenes.
# Set the default maximum gold in the module below.
# Set the default caps of items (when not set through notebox) in the module.
# Change the TEXT if you want for some reason.
# You can change the maximum amount of gold with the script call:
# $game_system.gold_max = x
# Where x is the maximum amount of gold.
# Set which items can have their item cap drawn in the below module. The
# available options are:
# :items
# :weapons
# :armors
# New in 2.1: no longer crashes upon entering equip scene.
# New in 2.2: no longer crashes upon entering shop scene.
# New in 2.3: draws item name more efficiently.
