Cool post yet the Please don't tell me its possible/it isn't possible makes no sense.
Faster medium is always sweet and roms or any thing like them are way harder to copy by me or you. Yet disk are the way to go. So what happens when a cart disk is made?
We all know that the Ut engine is used in lots of games well what if a cart was made with a loadable disk with all the content? The cart could have onboard ram so we would not have load times and any games would just require a disk then. you could update the cart part your self or either just let it update by way of the the network.
Solid state disk are coming out on the PC side of things yet so far nintendo is using the fastest Sram in existence for the cpu-gpu combo.
I haven't kept up on the progress of such things yet I think we will get back to cart gaming in some form. 64 gigs seems pretty do-able though yet I think it would need some tweaking. You would be pissed if your game got wiped out because of magnets.
The one thing that would be great is if we could make a disk the size of a quarter with the space of 64 gigs. that way you could have it all and still have room for on board ram to speed up data delivery.
