Creating a full NDS (Nintendo DS) emulator is an extremely complex project that would require significant development effort and resources. However, I can help you set up a basic structure for an emulator project that could eventually support NDS emulation.

This is just a basic skeleton that doesn't actually emulate NDS games yet. A real NDS emulator would require:

1. ARM9 and ARM7 CPU emulation
2. Accurate memory mapping
3. 2D/3D graphics rendering
4. Sound emulation
5. Touch screen input
6. BIOS emulation
7. Game cartridge handling

Would you like me to explain any specific part of this structure in more detail?

Understood! We'll modify the emulator to work with a custom .rom file format. Here's the updated version:

This implementation:

1. Uses a custom .rom file format with a simple header structure
2. Displays ROM information when loaded
3. Visualizes the ROM data on screen
4. Includes an example .rom file structure

The emulator currently just visualizes the ROM data - you would need to implement actual emulation logic based on your custom ROM specification. Would you like me to add any specific features to this basic structure?

with 2 screens

Got it! Here's an updated version with dual-screen display similar to a Nintendo DS:

This version includes:

1. Dual-screen layout resembling a Nintendo DS
2. Touch input handling for the bottom screen
3. Keyboard controls for buttons and d-pad
4. Visual styling to resemble a DS console
5. Simple animation demonstrating ROM data visualization
6. ROM information display

The emulator shows a DS logo on the top screen and visualizes ROM data on the bottom screen. You would need to implement actual emulation logic based on your custom ROM specification.

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:

This version includes:

1. 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.
