There's standard SNES controller support as well. Not just the NTT Data controller. Looks like L and R are used as shift buttons since multiple functions had to be mapped to each button to accommodate everything.
I wouldn't recommend it for games that involve keypad use during gameplay, but many Colecovision games only require the keypad to get into a game. For those games, a SNES compatible controller will be a fine option. Just remember that L + Y is mapped to the Colecovision's #1 key (Typically what one has to press to start a single player game at the default difficulty).

It doesn't support the Atari 2600 expansion module or the ADAM expansion module. It does support the driving controller, the roller controller, and the Super Action controller. The unreleased Super Game Module from back in the day that Opcode brought to fruition a few years ago is incorporated directly into the Colecovision core. So any SGM homebrew cartridges or roms will be compatible without need of the physical Super Game Module.
There's a built-in Atari 2600 core as well. It's far from perfect as-is (Although there are plans to polish it up), but you can at least play 2600 roms on here. And there are also plans to incorporate an ADAM core with a future firmware update.
