>>6017010If you just want that particular effect Look up the sprite sheet for sonic 3 blue sphere. It’s all animation frames cleverly looped, practically no scaling or sprite warping.
There are other effects you might want to look at though specially for the genesis since it had no way of rendering polygons they had to get clever.
Codingsecrets is a YouTube channel that covers a lot of neat sprite warping effects to achieve 3D looks, though he only covers the basic and usually only explains the theory of how effects the effects work
Last thing I can say to help is to consider looking at a full list of games for arcade, genesis, snes and gba. There’s a couple of standouts with nice 3D effects, mostly racing and sports games. Doing this I found moto racer advance, which uses a refined mode7 like system that calculates for height using something like a topographic map and does it while running at a smooth 60 fps too
