In case you're having trouble setting it up correctly, here's how it works:
1. Download r64 (http://code.google.com/p/smsplus-gx/downloads/list) and put it in the root of your SD card
2. Create a directory called '/smsplus/roms' and place your Colecovision roms in there
3. Put the Colecovision BIOS renamed to 'BIOS.col' in '/smsplus'
4. Fire it up and navigate to Emulator Options >> System Options >> Console: switch the setting from 'AUTO' to 'COLECO'
5. You're done
The Side/Action Buttons of the Colecovision controller are mapped to A and B.
In order to use the Keypad Buttons, use the R-Trigger to change current numeric value (from 0 to 9, #, *) and the L-Trigger to select the current value.
Hint:
For a more focussed / less distracting rom selection, you can leave out the file extensions of your roms. It should work just fine!
