You can play 1 button games without any mods just like with a 2600 joystick. For two button games, You would have to extensively rewire the insides according to the ColecoVision pinout and add diodes to both lines going from pin 6 to Pins 8 and 5. Pressing button 1 should connect pins 6 and 8 and pressing button 2 should connect pins 6 and 5.

And as mentioned, depending on the functionality wanted/required, either none, some, or much re-wiring is required, and either no, some, or up to 34 diodes may be required...again depending on what you want it to be able to do (1-4 "game" buttons, and 0-12 keypad buttons).
