## Screenshots

### Desktop

 

 

### Browser(Web)

    

## Features

- GB(DMG) and GBC(CGB) support

- Sound(APU) support

- Libretro support(run `make libretro`)

- Multiplatform support

- Work on Browser([here](https://dawngb.vercel.app/))

## Usage

- Desktop: Run `go run ./src/ebi` and drag and drop a ROM file into the window.

- Browser: Visit [here](https://dawngb.vercel.app/).

Key mapping is as follows:

- `A`: X

- `B`: Z

- `Start`: Enter

- `Select`: Backspace

- `↑` `↓` `←` `→`: Arrow keys

## Internal

```sh

.

├── core  # Emulator core

├── src   # Frontend

└── util  # Utility (should be renamed to "internal" in the future)

```

## Accuracy

Keep the code as simple as possible, so synchronization is done at each instruction, and line-rendering is done at once on HBlank.

So game like "Prehistorik Man", which modifies the PPU registers during mid-frame, may not draw correctly.
