You mean like a 2D mode, and a 3D mode?
That would be cool, and I have thought of the same thing...
I think the next roster should have like a demo in 2D just to show them off.
Since most likely 2D will never be seen again...
BTW I don't think it would take that much space from the memory.
If they made it just right they could syncronize the memory capacity taken to it. Then it would stay the same... The chances of Midway doing that?
1 out of a million XP.
I miss the 2D days.
