Today, the 640x360 Java game is a relic of "transitional tech." It sits between the charming abstraction of 8-bit pixels and the hyper-realism of modern Unity-based mobile games. Its legacy persists through:

• Native viewport: use a fixed logical canvas at 640×360 to keep pixel-perfect art and consistent gameplay.
• Scaling to screen: render to an offscreen BufferedImage or FrameBuffer at 640×360, then scale with nearest-neighbor for pixel art or linear interpolation for smooth sprites.
