I've touched on this before in other mailbags when talking about Zelda remakes/updates, so I guess I can say it again. Capcom/Flagship was always hazy about the number of GBC Zelda games they were going to make. They had planned on making 3 GBC Zelda games in the "Mysterious Acorn" saga (changed to Oracle) and there was talk of a Zelda 1 remake... it may or may not have been the third in the series. But whether or not they were one and the same, the third "Mysterious Acorn" title and the Zelda 1 remake were scrapped. Nintendo and Capcom claimed it was difficult enough to create two password-interlocked titles, so they supposedly took the third title and incorporated bits and pieces into the first two. As for the Zelda 1 remake, it was canned primarily because it was too hard to play on such a small screen. Whereas Mario titles could be finessed to run on a smaller screen (due to their scrolling nature), the original Zelda's room layouts proved impossible on the smaller screen: players often couldn't tell where to go or what to do... So it was canceled. You may have recognized updated versions of Zelda 1 bosses in Oracle of Seasons, and I propose these are leftovers from the Zelda 1 remake.
