My jaw dropped when I saw how many lines of code it took to make A Link to the Past. That may not sound like a lot today with developers that fall back on engines and such with unoptimized code or whatever but back then, the early 90's, I am sure that was A LOT of code.

What is even better about this port is, developers can add and remove things as they see fit and code them in. If someone was ingenuitive enough they could add a two player mode, new enemies, levels, etc.

The possibilities are almost endless.
