" I live deep in the mountains"
That's... potentially interesting. I live on top of mountains, too. (Unless you mean living deep "inside" mountains.)
If you don't mind heavier spoilers, I can get more specific:
-item from the end of the Oasis level (the one that requires the L2 hammer to go anywhere inside), so, northwest of Grain. It's dungeon item was the best arrow, if you beat it all the way, you get one of the items you miss
-L03, north corridor. Bomb left, just as you did with a similar south corridor
-L06, south from start, in the majestic secret area. You definitely seen it, just you probably haven't killed all enemies there
-Babylon. A statue keeps shooting fireballs, reflect them back to the odd shield.
That's all you miss in this playthrough. Next time you can get more by not getting flute, fire racket and magic shield for as long as possible, also by not having the L1 hookshot and L1 hammer at the very same time.
Fortunately, Valami is not just for hardcore players. I really could have made something that indicates which dungeons you found and which you haven't and how many items are still in there, but I wasn't THAT script-heavy back in 2013 and in the beginning of 2014.
