EmeraldMinex (or Emerald Mine eXtended) is an extended Windows port of the Amiga game Emerald Mine and

EmeraldMinex is freeware.

Features:
- Over 50,000 levels from the Emerald Web playable
- Level browser with preview for quick navigation through all these levels
- Compatible with EMC version 6
- Integrated level editor
- Control with cursor keys, WASD or game controller
- Rewind time with page up and page down keys
- Automatic and manual save points
- Slow down and speed up time with left and right shift key

- Low requirements: still runs on an older Windows (tested on Windows 10 / 7 / XP / 98) and
