The glitch is the only way to obtain the earliest hammer and the Dream Harp in the NES version. In order to do so, the player should apply the glitch once to a Madhura Harp to get a Dream Harp, and twice to a Rune Staff to get the Hammer (although, in this latter case, it is a downgrade). Both the Madhura Harp and the Rune Staff can be purchased in shops short after obtaining the jobs that can use their upgrades.
