The DS has two 256×192 pixel LCDs. That’s tiny by modern standards. The problem isn't size; it's synchronicity. Many games (like The World Ends With You) use both screens simultaneously for real-time combat. If the top screen renders 2 frames behind the bottom screen, the game breaks.

JavaScript’s requestAnimationFrame runs at 60fps, but the garbage collector can pause execution for 5-10ms. In a native emulator, that’s a stutter. In a JS emulator, that’s a desynced dual-screen nightmare.

Solution: Modern emulators use OffscreenCanvas and WebGL textures to update both screens in a single GPU draw call, bypassing the main thread for rendering. nintendo ds emulator js
