I wonder how they'll actually do a DLC for Genesis... if it'll just be an extra already included on the cart, or if they'll do something crazy with the cart connecting to the internet somehow
Most likely just an extra already included on the cart.
If it is, the release date could be delayed since they had to add that in the rom before flashing in cartridhe.
The one who planned DLC with the cart connecting to the internet is
PAPRIUM back then.
Not just online DLC, but also network play, online updates, MCD AI and a DSP.
But those plans never came into fruition.
