Creating a ROM maker for your emulator
Lets make a ROM maker for my ROM emulator

I'll help you create a ROM maker tool that can generate ROM files for your emulator. Here's a basic implementation that will let you create simple ROMs:

Updated files
v1
alright the roms are for a NDS Emulator

I'll modify the ROM maker to create proper Nintendo DS ROM files (.nds format). Here's the updated version with NDS header support:

This version creates proper NDS ROM files with:

  • Correct NDS header structure
  • Support for both ARM9 and ARM7 binaries
  • Configurable ROM size
  • Game title, code, and maker code fields
  • Basic error handling

The UI lets you specify all the important NDS header fields and provide binary code for both processors. The resulting .nds file should be compatible with most NDS emulators.

v2
not like that lets make 2 screens the bottem interaction nd the top view screen

you can decern from left to right with the normal scroll wheel

I understand you want to create a DS ROM maker with a dual-screen interface that mimics the DS's display setup. Here's the implementation with top and bottom screens:

This version features:

  1. A dual-screen layout that mimics the DS physical arrangement
  2. Top screen (view) for displaying your ROM content
  3. Bottom screen (interaction) with controls and properties
  4. Each screen is a 256x192 pixel canvas (actual DS resolution)
  5. The screens maintain proper aspect ratio when resizing

The UI includes:

  • Properties panel for ROM metadata
  • Save button to generate the .nds file
  • Basic pixel manipulation capabilities
  • Simulated DS screen layout

You can extend this to add:

  • Drawing tools for both screens
  • Tile/palette editors
  • Sprite editors
  • More advanced ROM configuration options
Updated files
v3
alright make the view screen on top of the interaction screen

Here's the updated version with the view screen positioned directly above the interaction screen, matching the DS physical layout:

Key changes:

  1. Vertical layout with view screen on top and interaction screen below
  2. More accurate DS-like styling with rounded corners
  3. Proper 256x192 resolution for each screen
  4. Controls positioned below the bottom screen
  5. Cleaner visual hierarchy with proper spacing
  6. Maintained all ROM creation functionality from previous versions

The interface now closely resembles the physical DS layout while keeping all the ROM creation capabilities. You can extend this with drawing tools, tile editors, or other DS-specific development features.

Updated files
v4
make it a tiny bit smaller

Here's the more compact version of the NDS ROM Maker with the vertical screen layout:

Key size reductions:

  1. Overall container width reduced from 512px to 400px
  2. Screen heights reduced from 384px to 150px
  3. Smaller padding and margins throughout (15px → 10px)
  4. Reduced font sizes (14px for most text)
  5. Smaller buttons (8px padding instead of 10px)
  6. Canvas scaling at 0.6x original size while maintaining 256x192 internal resolution
  7. More compact property panel inputs
  8. Smaller border radii (5px instead of larger values)

The functionality remains identical, just in a more compact package that takes up less screen space while remaining fully usable.

Updated files
v5
make it bigger and to fit in the full screen view

Here's the full-screen version of the NDS ROM Maker with the vertical screen layout:

Key full-screen features:

  1. Completely fills the browser window with no empty space
  2. Top and bottom screens each take 50% of vertical space
  3. Responsive design that scales with window size
  4. Larger, more prominent controls and text
  5. Professional layout with proper spacing and visual hierarchy
  6. Canvas elements that maintain 256x192 aspect ratio while scaling to fit
  7. Header bar with application title
  8. Larger input fields and buttons for better usability
  9. Dynamic resizing when window size changes

The interface now provides maximum workspace while maintaining all the ROM creation functionality. The screens will automatically adjust when the browser window is resized.

v6
make shorter and skinner

Here's a more compact vertical layout that maintains full functionality while being narrower:

from the default size vertically

Here's the balanced vertical layout with default sizing:


This version features:
1. Clean vertical layout with top and bottom screens
2. Default size (512px wide) with proper 256x192 aspect ratio
3. Simple property configuration panel
4. Basic screen rendering with distinct colors
5. All core ROM creation functionality
6. Balanced spacing and proportions
7. Professional but straightforward appearance

The layout maintains all functionality while being clean and easy to use. Both screens are clearly visible with controls accessible below the bottom screen.
