|Final Fantasy III|
Final Fantasy III is, of course, the third game in the Final Fantasy series. Unfortunately, it didn't get released in America until the Nintendo DS era – the SNES III was a renumbered Final Fantasy VI, and Square skipped it while rereleasing the series on PlayStation (the three compilations were I and II; V and VI; and IV and Chrono Trigger) - III's omission is supposedly due to the loss of the original source code.
Steal more info from FFWiki or something. Some good info here, and this site has some info on the NES enemies.
Hold Up + Left + Start + Select, press Reset, then release Select to display the message "BY: NASIR" (Nasir Gebelli, the game's programmer). Presumably, he could have used this code to prove the game was his if a pirate were to remove the game's credits.
All of these locations are present in the game but the location text went unused.
"Ancient Ruins Investigation Unit"
"Great Ship Invincible"
"Behind the Waterfall"
A lightning-elemental hammer with 25 attack power, and 60% hit rate. Can be equipped by Viking. It can't be found, stolen, bought, or won from enemies, but it can be obtained through a glitch. It ended up being used in the DS remake.
A harp with 0 attack power, 60% hit rate, and can cause sleep. Can be equipped by bards and ninjas. It can't be found, stolen, bought, or won from enemies, but it can be obtained through a glitch. It ended up being used in the DS remake.
Level 34 with 315 HP, gives 410 XP and 800 Gil. Doesn't have any spells or elemental affinities, and it doesn't have any items to drop or steal. Has an alternate palette for some reason. Seems like there were supposed to be goblin enemies on the surface overworld, judging from its stats.
32 Magic Defense
Its HP places it around the final areas of the game, maybe the Ancient's Maze or as part of formations in the Crystal Tower, though given its relatively low level it could have appeared as a powerful enemy earlier on, which is also supported by its relatively high Gil drop. Either way, the dummied-out status of this and the Captain means that at some point they decided to make Goblins exist only on the Floating Continent.
Level 35 with 330 HP. Gives 960 XP and 440 Gil. Weak to Ice and Wind, and can cast Fire. Can steal Potions from it. Definitely the most complete of the dummied enemies. Stats place it somewhere on the surface world as a random encounter, or perhaps earlier as a boss.
Level 64 with 1140 HP, gives 4600 XP and 4400 Gil. Can steal Potions. This one was definitely in the Ancient's Maze.
Apparently there's a third palette, but I can't find it.
208 Magic Attack
18 Magic Defense
Has no items or elemental affinity, but it does have is a Strength of 150 - higher than even the final boss! Seems like either a powerful Ancient's Maze or Crystal Tower enemy, or perhaps a superboss. It might have been removed for being too powerful, as the last few bosses are incredibly difficult already.
Level 30 with 265 HP, gives 560 XP and 310 Gil. Can steal Potions. Has no special abilities or elemental affinities. Apparently, this enemy was listed in Japanese guides. This enemy had its stats boosted and ended up used in the DS remake, as a random encounter in the Goldor's Mansion room with the Gold Swords!
Level 11 with 120 HP, gives 152 XP and 102 Gil. Steal potions, no abilities or elemental affinities, the usual. She was also put in the DS remake, as a random encounter in the first floor of Tower of Owen.
Can't find any substantial info on this guy. I'll try to fill out stats for him and the rest once I get to a computer that can read data, but if anyone knows anything...
This guy was also in the DS version, on the water in the northern part of the Floating Continent.
