Dont know if any repro's or fantranslated versions of mother use the real name or not ive only seen earthbound zero as to final fantasy differences heres a quote from this site
http://www.ffcompendium.com/h/faqs/ff1versions.txt[1.B] Famicom/NES Differences:
The vast majority of the names of items, spells, monsters, etc. were changed
from the original Japanese version. They can be found in the charts below.
Most changes were probably made to save space, some were for censorship of
religious references (Holy to FADE), some likely because of copyright reasons
(Beholder to EYE), and some were just stupid (Lizard to IGUANA). The 4
Chaoses became the 4 Fiends, probably to avoid confusion. Most importantly,
the ORBS in the English version were Crystals in the Japanese version. Gold
is called Gil, like in later games.
Some graphics were also changed. The man in the Church/Clinic has a hat with a
cross on it in the original version. The Church itself was changed; the heart
on the US version's Clinic was a cross on the Church. Most of the classes
have some minor differences in their battle poses. For example, the Super
Monk/Master has a different hair style. Medusas are topless, and the
Beholder/Eye & Death Beholder/Phantom look vastly different. Also, the
candles found in some places were crosses, and the triangles in Tiamat's room
were six-pointed stars.
The last floor of the Temple of Fiends/Chaos is empty in the US version, but
full of monsters in the original. Some minor changes: The Japanese version
does not let you skip past the story screen with the start button, and the
options in the weapon and armor screens were highlighted in red.
The version of FF1 on the FF1&2 cart is a cross between the Famicom and NES
versions. All of the names are the same as the first Famicom version, but the
character and monster graphics from the NES version are used. You can't skip
the story screen, the weapon and armor screens have red highlight like the
first Famicom version, and the monsters are missing from the final floor like
the NES version.
