Marat Fayzullin ported his very own Coleco Vision emulator ColEm for Android devices. As the program is still in beta testing, it’s free for the moment.

Changes:

* Published a separate ad-free ColEm Deluxe version.
* Now saving game state on exit, so that users can start where they left off.
* Changed virtual joystick layout to make fire buttonsmore comfortable.
