TEST PLAIN

''         The title of this article is incorrect because of technical limitations. The correct title is'' TEST_PLAIN

TEST_PLAIN is one of the earliest known courses created for what would soon become Super Mario 64. This level was most likely a test stage for the platforming engine of Super Mario 64 and for the capabilities of the early designs of the Ultra 64 console or a prototype stage for the cancelled Super Mario FX game for the Super Nintendo Entertainment System.

Appearance
TEST_PLAIN is dated back to December 1991. The course consists of a large square with two small platforms located on top. These two small platforms consist of a small two-step staircase and a rectangular platform on which Mario spawns when the level is loaded in. There are no stars in the level, no loading zones, no enemies or any objects aside from the terrain and the player.

The ground is textureless, appearing as pure white. The skybox is pure black when loaded in. There is no music either.

History
TEST_PLAIN was dated to December of 1991, and was created by a currently unknown Nintendo level designer as well as Mr. Seiyro, whom was a contributor to the product, although he did not do most of the work.

The course did not make it into any of the final builds of Super Mario 64, nor was mentioned in the level select screen.

TEST_PLAIN was found on a floppy disk in the attic of a different Nintendo level designer's home in Nagaokakyō, Japan by his family after he passed away. The course was leaked onto the internet and confirmed to be legitimate by his co-workers. It was not stated which console the course was for in the original leak, and the file format was one not compatible with either the SNES or the Nintendo 64.

Trivia

 * The TEST_PLAIN course could very likely be an early version of the MEADOW stage from the Sombrero Build.
