It’s not too bad. Just map the c buttons to the right analog stick (like the GameCube controller), z to l1 and l to l2, and f to r1 and it feels pretty natural. (That’s basically how they did it for the GameCube ports except they put o to the digital pad up because all you use it for in these games is to toggle the on screen map on or off). I actually prefer it to the original that way.
And the packs I use don’t really change the feel of the game they just make the textures more detailed.
