I have released ColEm-Android 3.4 this morning. This release brings ColEm in line with my other emulators, adding full fledged support for AndroidTV and other gamepad-only devices. You no longer need the touchscreen to operate the keypad, file selector, key mapping dialog, and other features.

• Optimized app for AndroidTV, tested on the ADT-1 box.
  
• Virtual keyboard can be operated with gamepad.
  
• Added overscan border on AndroidTV devices.
  
• Added hints to the emulator and key mapping dialog.
  
• Fixed crashes on devices with no web browser (e.g. ADT-1).
  
• Replaced AndroidTV banner image.
  
• Enabled gamepad-only emulation interface.
  
• Press BUTTON_R1 to invoke File Selector context menu.
  
• Press BACK on gamepad to exit emulation.
  
• Press MODE or BUTTON_A+BACK to open menu.
  
• Press BUTTON_X if you have no SELECT button.
  
• Press BUTTON_Y if you have no START button.
  
• Xperia CIRCLE button now acts as BUTTON_B.
  
• Redesigned key mapping dialog.
  
• Press same key twice to remove it from assignments.
  
• Press same key three times to confirm key mappings.
  
• DPAD_CENTER key no longer confirms key mappings.
  
• Added "General | Reset All Settings" option.
