The Knowledge

There's a yellow block located in room 14 (1 room north of Kolorado's Camp). This block has a counter that is tracked in the game's memory, which increases by 1 each time it is hammered without changing rooms.  It's a RAM value that can store the numbers 0 - 4,294,967,295 (unsigned integer).  Each time you hit the middle box, the value of the associated memory address increases by 1.  When you hit it once, the mushroom box appears.  Hitting it ten times causes the Super Shroom to appear, and hitting it 100 times causes the Ultra Shroom to spawn.  There are no other Mushrooms that appear; however, what if someone were to hit it 4,294,967,295 times?  The value of the memory address would overflow and loop back to 0, allowing you to obtain all three of the mushroom items again (technically, this means there is a method of obtaining infinite Ultra Shrooms in the game without glitches or hacks).
