You are talking about demoscene stuff which has no place in games, or polygon games which i really don't give two asses about ;D
Besides that, anything else? I still don't get the advantage.
Do you need to put routines in work RAM?
The whole game code needs to be put in 64KB or can it be kept in the cart and "loaded" at times? Isn't that where the cart advantage starts? The code needs not to be loaded since it is in a ROM and can be accessed as fast as RAM?
again, excuse my ignorance, but I want a deeper explanation, this intrigues me
