PROJECT REALITY MARIO BROTHERS

PROJECT REALITY MARIO BROTHERS is the codename for a tech demo which may have been shown at the Project Reality show in 1993. This may be one of the many early prototype builds of Super Mario 64.

Development began on the August 16, 1993 and was scrapped in June 26, 1994 for Ultra 64 Mario Brothers based on information found in a document for the tech demo. This build may have also been created before the Personalisation A.I. According to reportings by a person present at the Project Reality demo, the game shown was in a incredibly barebones state.

Features
According to mentioned person at the show, the game immediately cut to level select after the title screen with the words 'PROJECT REALITY MARIO BROTHERS ' in a green font with a 3-dimensional effect. The levels were, as mentioned:

MEADOW, CITY, WATER, LAVA, KUPPA, BROTHER

There may have been more included, this was from the reporter's memory.

Meadow
A grassy area with a large mountain, probably the original version of Bob-omb Battlefield. The reporter described it as 'incomplete and lonely'. A single 2D picture of Yoshi (from promo-art for Super Mario World) exist in the level. The game is played from Mario's point-of-view, making the use of a Mario model useless.

City
The most detailed of the levels, a 3D rendered city with multiple streets, avenues and buildings. The first known instance a Super Mario level was set in a city; the concept was never used in Super Mario 64. 2D images of multiple Nintendo characters scatter the level, which was reused in another test demo.

Water
A possible early version of Dire Dire Docks or Jolly Roger Bay, using much more advanced graphics than those from the final game. Instead of Unagi the Eel, A 3D model of a shark is existent in the level. Once again, the level was reused in another demo.

Lava
Unseen level, probably the origin for Lethal Lava Land.

Kuppa
An incredibly detailed version of one of the Bowser battle arena; resembling one from a piece of Super Mario 64 promo art. A 3D model of Bowser exists in the level, based on later renders for Super Mario 64.

Brother
A flat and never-ending level with the Eternal Star statue. The reporter described the level 'having potential'.
