I tried it out in version 819 and played the first level with no problems. Too easy but I know you will probably change things around as you add to your quest. I had only 3 little problems after finishing level one. I got what I thought was a magic bottle in the dungeon, but the magic meter never showed up. Then after getting the triforce and caming out of dungeon I started in the wall but I could easily take a step to the right and be back to where I should be. The other problem was after leaving the 1st dungeon nothing showed up in the A or B part of the inventory. It just disappeared. I still had everything in my inventory and even though I selected the sword and boomerang it wasn't showing there but I could still use everything I had. Got the hookshot and chose it but had the same disappearing problem. It did work when I chose it. I never did find the second level but it was fun to try it out the first one. All in all not to bad for the beginning of a quest.
