Heres a new colecovision emulator for android, here the release details:
ColEm 4.2.4 for Android, a new version of my ColecoVision emulator, has been released yesterday. The new release improves the replay feature, by adding remaining time display and fixing bugs. I have also made Settings use textured backgrounds, like the rest of the app, since users asked for it. See below for all the changes.
Added remaining time display during replay.
Fixed replay rollover mechanism.
Added shadow underneath the time display.
Settings activity now uses black/white UI setting.
Switched Settings to Material Design on Lollipop+.
