Well, the great thing about these wireless controllers, is that they said all 3 Sega controllers, will be compatible on all 3 Sega systems they are made for. So for instance, say I want to use this beauty on the Dreamcast with the DC dongle, it will absolutely sync up to it.
That one still isn't out though, and it will be my go to controller for PS3 since it will also be compatible with it. But for sure the Saturn and future DC controller is going to rock. Also, the Start and Select buttons will be swapped in the final version.
Also, odds are that it could be possible too flash the firmware on the dongles to hack in support for Xbox One and PS4 controllers. THAT would be pretty cool.
And sorry if it seems I am posting a lot about this, I had a mega thread about it over at Assembler been eating up every ounce of info since they announced the partnership in January 2018. https://assemblergames.com/threads/retr ... led.68063/
