Main differences with the original project:

• Added logic to toggle sound.
• Added logic to load and save game state files.
• Implemented logic for pausing the emulator on blur and resuming on focus.
• Implemented a workaround that replaced ScriptProcessorNode (deprecated).
• Migrated the build to code compatible with pre-ECMAScript 2015 environments.
