I've found a problem in the zelda hack.
There's this one place under the guard house in the beginning that has one of those red/blue switches.
Apparently you're supposed to use the boomerang to hit it.
I say apparently because I was able to get past the blue/red pegs affected by the switch without using the boomerang by using a spin attack to hit the switch from a small distance.
I didn't even know there was a boomerang down there until I read the readme.
When I found the "big chest key" down there I just assumed it was for the big chest in the first floor of the guard house since I didn't see any other chests, though I apparently missed one down where I got the big key.
well, point is that I got out without the boomerang, and since the place seals off after exiting with zelda there's no way to go back in and get it.
I'd take a pic of the place exactly that it happened at, but like I said, it's sealed off now.
Guess I should go back and take a pic after all, but I hate doing things repeatedly.
I don't know how important the boomerang is in later parts of the game, but I can guess.
