I'm sorry but you may have misunderstood. That's completely wrong. It is more time consuming to port downwards.

Fixed point coordinates perhaps? It's possible to have a 50 hz game update on screen objects with fractional fixed point values. That way every object doesn't have to move at a linear 50 fps.

He's using the halftone/smudge mode for some free effects in real time. Looks like it maxes out at 16% CPU time. Impressive!!!

AGA is outclassed by the Megadrive for scrolling games. Far more sprites and twice as many 16 colour scrolling layers. The dictionary definition of too little, too late.
