Emulator Integration

Playback uses industry-standard emulator technology to play your games with excellent accuracy and performance.

How it works

Playback is built on the libretro API, a cross-platform standard that provides a consistent interface for emulators. This technology allows:

• Seamless integration of different emulator cores
• Consistent input handling across cores
• Cross-platform compatibility

Core selection

Access core selection by going to Settings > Core Selector.

Automatic (recommended)

Playback automatically selects the best core for your device:

• GB Operator: mGBA
• SN Operator: bsnes

This is the default and recommended setting for most users.

Manual selection

Choose a specific core from the available options. Each core has different features and trade-offs.

Custom cores

Load your own libretro core file:

1. Go to Settings > Core Selector
2. Select Custom Core
3. Browse to the core file on your computer

Important: Custom cores must match your system architecture (AMD64 or ARM) and operating system.

Emulator cores

These cores are officially supported and offer excellent accuracy and compatibility.

Core features explained

Choosing a core

Use the default cores (mGBA for GB Operator, bsnes for SN Operator). They offer the best balance of accuracy, features, and compatibility.

Note: mGBA supports RetroAchievements. bsnes does not support RetroAchievements, but other SNES® cores are available that do.

You can view the licenses for all included software in the Licenses section of Playback’s settings.

External emulators

If you prefer using a different emulator, you can:

1. Back up your game using the Data tab
2. Open the backup file in your preferred external emulator
3. Save files created by Playback are compatible with most emulators
