Unlimited Save Files

Introduction
This script allows you to have unlimited save files. Only four files are shown at once, but the list can be scrolled. To choose the maximum number of save files for your game, change the value of the constant SAVEFILE_MAX at the start.

To use this system with the overwrite confirmation script, place the overwrite confirmation script BELOW this one for the two to work properly. This is assuming that both scripts were the revised versions in this forum. Any other difficulties and it is your responsibility to combine these scripts.
