These are just my opinions, but here are some things I'd like to see:

- The overall format of the quest stays the same: 9 dungeons, must complete 1-8 to access the 9th.

- Standard quest rules (1st + 2nd quest) and classic tileset.

- All of the classic Z1 items should be present, but new items such as the hookshot are allowed. I'm not sure what items are available nowadays, so there may be need to be some exceptions to this rule.

- No scripting or cutscenes. This is to keep the presentation consistent with Zelda 1.

- Overworld should be the same as in the 1st and 2nd quest, with the allowance for 2 screens to be modified. Modifications should be free-form (not have to be a copy of some other screen on the overworld).

- Dungeons design (block placement, enemy types) should be up to the quest creator. New enemies should be allowed (within reason, as with new items). Any dungeon can have up to 2 items, to make room for any new items included.

- Link starts in the same screen as usual, and the first cave contains the Wooden Sword. Please none of this "swordless Link" bullshit!
