Backlog Buttons #

In addition to standard on-screen buttons, VNgen provides a separate set of button functions specifically for the backlog. Both button types are functionally identical and even share a single set of IDs, but with one key difference: log buttons are only enabled while the backlog is open, and other buttons are only enabled while the backlog is closed.

In this section we’ll examine available backlog button functions, which can be used to scroll the log, close it, or even act as a full pause menu.
