Yes, that's a good point and one I admittedly missed when looking through the submission. Looking further at the discussion I think the timing constraints on the swap are too tight on real-life hardware for manual swapping to be feasible, unfortunately :( From what I think are initial console verification attempts:

> With a cart that sets RAM to the initial state, I can get to the 'N' worlds about 1/4 times on console, but then it crashes at Bowser. I imagine I need a more sophisticating swapping technique then manually to get it to work. The probability of none of the bits decaying away in the time it takes me to swap is probably very low.
