Retrobator

Retrobator is a new NES emulator that brings some fresh features to the table.

Key Features:

• Timeline - Your personal time machine: go back seconds, minutes, or hours, then replay or restart from any moment.
• AutoMap - The world draws itself as you explore, viewable at any time with zoom and pan controls.
• Sprite Replay - Little ghost-sprites reenact your past triumphs (and face-plants) on top of the map.
• Custom Backdrops - Personalize games with your own background images via color keying.
• Motion Interpolation - Enhances smoothness by inserting extra frames between existing ones.
• AI Assistant - Plug in an AI sidekick for voice commands, banter, and other sorcery. *OpenAI API credit required.
• Pressure-sensitive fast-forward, rewind, and slow-mo via gamepad triggers.
• High-resolution, unmixed audio waveforms with octave control.
• Input lag reduction, CRT-style filter, sprite trail effect, built-in cheats, and more!
