Realistic DS Emulator

make it wrap around and stuff and add side hinges and you know what i mean yeah yeah yeah Got it! Here's the full DS emulator with realistic styling, including the hinge and wrapping around the screens: Realistic DS Emulator

No ROM loaded

Realistic DS styling with proper wrapping around screens 2. 3D effect with hinge between screens 3. Visual representation of all input buttons (D-pad, A/B/X/Y, L/R) 4. Touch input support for bottom screen 5. Power LED and speaker grille 6. Improved ROM visualization with particle effect on top screen 7. Better touch input handling with coordinate scaling 8. On-screen display of ROM information and FPS 9. Clickable on-screen buttons with visual feedback The emulator shows a realistic DS console shell with opening/closing animation and all the controls of a real DS.
