A critical evolution in the use of Gen 4 tilesets is the adoption of "parallax mapping." In the native DS games, the tiles appeared somewhat constrained by the hardware. However, within RPG Maker XP and Essentials, developers have unlocked the potential of these assets by breaking the rigid grid. By using parallax scripts, creators can layer Gen 4 assets to create true depth—placing trees in the foreground and cities in the background with independent scrolling speeds.
