Plaid Berries!
The item get popup appears to be the same basic design, though the pattern in the background was plaid rather than checkered...

Characters
A list of characters on the select screen. Obviously within Dry Dry Ruins.

Button
The button in Dry Dry Ruins did the same thing before as it does today...

Goomba King
A VERY early picture. Shows the old, almost Super Mario RPG-esque status of Mario. He's got a lot of HP for this part of the game...

Koopa Attack
The battle menu design is more alike it is today, though still with the hearts rather than the fraction.

Koopa Attack 2
This apperrs to be from the same battle sequence as the previous picture. However, the HP displays are the major difference here. Rather than small bars they are really actual hearts. I can only image what Bowser's was at 99 hearts...

Koopa Bros
This shot is most likely from the point where the Koopa Bros speak with Bowser. The only real difference is that Bowser's cheeks have an odd shading effect.

Menu
The menu is very similar to the final version of the menu. Though, you'll notice Mario is level 0.

Open Battle
An early battle scene. The background is very underdevelouped. And, also, the original style of battle stats is used here.

Mushroom Kingdom
Toad Town was, at one point, named like it was in Super Mario RPG...The Mushroom Kingdom.

Six Pictures
A collage of six different pictures. Many of them are very interesting, ranging from enemies that never appeared to scenes and places that were never in the game.

Super Mario RPG 2
A title screen that, obviously, was from the time when the original name of Super Mario RPG 2 was to be used. The world map behind the clouds is very similar to the end game's world map.
