05 / Picture
The original picture, on a modern screen.
Window mode, Fit and Integer Scale, aspect ratio, pixel filtering and effects come from Settings → Graphics, for every system or for one game.
- Resolution
- Drawn at its original resolution, then scaled to your window with Fit or Integer Scale and your choice of pixel filtering and effects.
- Sprite Limit
- Original Hardware by default, or Reduce Flicker. It changes the picture only.
- Renderer
- Shown for information. The system's built-in engine chooses how it draws, with a safe fallback.
06 / Your progress

07 / Play together
Together on one PC.

- Across PCs
- Not available. This system is local only.

Known limitations
- Only games on the standard Sega cartridge mapper are supported.
- Compatibility is limited to the games that have been tested.
