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:

* No longer need to provide system ROM.
* Added option to record music to a MIDI file.
* Added accelerometer support.
* Bigger, better labelled, easier to press on-screen corner buttons.
* Sony Xperia Play buttons are fully supported now (please, test).
* Fixed sync frequency computation for more precision.
* Fixed TV scanlines effect that got applied to more pixels than needed.
* Fixed accidental crashes when exiting emulation.
* Fixed About dialog reappearing on rotation.
