After a long pause, I have updated ColEm-Android, my ColecoVision emulator, to version 2.8:

The new version adds improvements and fixes previously introduced in my other emulators, such as Replay feature, improved File Selector, and reorganized menu system.

• Added Record/Replay feature letting you "rewind" gameplay.
  
• Merged Freeze and Restore into Freeze/Restore dialog.
  
• Collapsed all advanced menu items into Advanced submenu.
  
• Only showing File Selector progress dialog for large folders.
  
• Optimized File Selector labels and screenshots for smoother scrolling.
  
• Fixed NetPlay crash when own IP address cannot be detected.
  
• Fixed problem with NAT IP being reported to NetPlay instead of local IP.
  
• Made NetPlay a checkable menu item.
