Item description:

The purpose of this hack was to take the same approach Nintendo took with Ocarina of Time: Master Quest. Numerous Zelda games have a second quest in one form or another, and the author felt that A Link to the Past deserved a similar treatment. The dungeons have detours, rearranged items, tougher enemies, and an intermediate difficulty level. However, an optional “Double Heart Damage” patch is included for those looking for a greater challenge.
