This patch is for an unheadered 1.0 FF3 US rom

To make room for Czar Dragon's new sprite, some sprites had to be removed: Striker and Rough (the blades of Inferno in Kefka's Tower), the Critic in the Dreamscape, the Still Life in Owzer's Gallery, and the Raiden esper. All of these enemies have been given replacement sprites, and Raiden is now a palette swap of Odin.

If this patch is applied and a save file loaded where the Eight Dragons have already all be killed, you can still access the Dragons' Shrine via a failsafe. Go to the Coliseum, enter the inn, and step on the upper-right tile beside the counter; the Dragons' Shrine is now activated. This event checks to see if all Eight Dragons are dead, so it cannot be used until then, nor will it be usable if the Eight Dragons are killed after applying the patch (ie, you can't use this to try and reset the shrine)
