#1: In betas 163 (or earlier)-180, whenever you go to the init. data and decide to put a triforce piece in any Level number, it will not show up in Zelda Classic. This was tested in Windows.
#2: In beta 180, whenever you have Z3-Boomerang/HShot rule on and decide to fight a Goriya, the game crashes. This was tested in Windows; if this was reported, please disregard it.
(bonus bug) #3: Whenever you go to Zelda in beta 180, you can hit her with any weapon, like as with any other people. In the original, you can only hurt her with bombs. What the hell? Again, tested in Windows.
