+# GBEmulatorShootout 🎮
+
+A comprehensive comparison framework for testing Game Boy emulator accuracy across hundreds of test ROMs.
+
+## Overview
+
+GBEmulatorShootout automatically tests multiple Game Boy emulators against a suite of accuracy test ROMs, generating detailed HTML reports with pass/fail status and screenshots for each test case.

+
+## Supported Emulators
+
+The framework currently supports testing the following emulators:

+
+## Test Suites
+
+The framework includes test ROMs from multiple sources:
+
+- **Blargg's tests** - Classic Game Boy test ROMs
+- **Mooneye tests** - GB/GBC accuracy tests
+- **Acid tests** - GPU/graphics tests
+- **Samesuite tests** - Various test scenarios
+- **ax6 tests** - Additional accuracy tests
+- **daid tests** - Custom test collection
+- **hacktix tests** - Edge case tests
+- **cpp tests** - C++ emulator tests
+- **mealybug tests** - Timing and accuracy tests
+
+## Requirements
+
+### Core Requirements
+```
+pyautogui
+pillow
+requests
+pywin32
+selenium
+tqdm
+```
+
+Install with:
+```bash
+pip install -r requirements.txt
+```
+
+### System Requirements
+
+- Windows (for most emulator automation)
+- Python 3.7+
+- Game Boy emulators installed and configured
+
+## Usage
+
+### Basic Usage
+
+Run all tests on all configured emulators:
+
+```bash
+python main.py
+```
+
+### Filter by Emulator
+
+Test only specific emulators:
+
+```bash
+python main.py --emulator mgba --emulator sameboy
+```
+
+### Filter by Test
+
+Run only specific test categories:
+
+```bash
+python main.py --test blargg --test mooneye
+```
+
+### Filter by Model
+
+Test only specific Game Boy models:
+
+```bash
+python main.py --model DMG    # Original Game Boy
+python main.py --model CGB    # Game Boy Color
+python main.py --model SGB    # Super Game Boy
+```
+
+### Get Startup Time Measurements
+
+```bash
+python main.py --get-startuptime
+```
+
+### Get Runtime Measurements
+
+```bash
+python main.py --get-runtime
+```
+
+### Export Test Data
+
+Export emulator and test definitions to JSON:
+
+```bash
+python main.py --dump-emulators-json
+python main.py --dump-tests-json
+```
+
+## Building Reports
+
+After running tests, generate an HTML report:
+
+```bash
+python build.py
+```
+
+This creates `index.html` with a detailed comparison table showing:
+- Pass/fail status for each test
+- Screenshots of test results
+- Overall accuracy scores per emulator

+
+## How It Works
+
+1. **Test Discovery**: The framework discovers all available test ROMs from various test suites
+2. **Emulator Setup**: Each emulator is configured and prepared for testing
+3. **Automated Testing**: Tests run automatically using pyautogui for UI automation and screenshot capture
+4. **Result Analysis**: Screenshots are compared against expected results
+5. **Report Generation**: Results are compiled into an interactive HTML table
+
+## Adding New Emulators
+
+To add a new emulator:
+
+1. Create a new file in `emulators/` implementing the base emulator interface
+2. Add the emulator specification to `EMULATOR_SPECS` in `main.py`
+3. Implement required methods: `setup()`, `run()`, `undoSetup()`
+
+Example emulator specification:
+```python
+{
+    'factory': lambda: _new_instance("emulators.myemu", "MyEmulator"),
+    'keywords': ["MyEmulator", "myemu"],
+    'name': "MyEmulator",
+    'url': "https://myemulator.example.com/",
+}
+```
