Final Fantasy 1 that was released in Japan in 1987, 3 years later for NES in 1990 had many changes made, for example, the Church cross was removed and replaced with a heart, the priest inside no longer wears his mite. The Star of David and church crosses in the Earth Cave, Ice Cave, and Sky Palace, has been replaced with Delta Triangles, and Candles. The Medusa monster being topless was covered up in the NES version.
However the church cross on the Shield icon armor menu remains unaltered.
