Build 039

Build 039 refers to a build found in the hard drive of the Redmond Collection. The build seems to be a demo planned for Spaceworld 1995, but has a file date from December 14th, which is after the event. This could be theorized to be the last time the file was opened. However, according to a .txt file found in the source code, Stanley, the supposed only employee who worked on this build, left on the 8th, but still tried to finish the build for Argonaut and Nintendo before he quit working. The build itself holds a lot of differences from the final, and even other earlier builds. It needs the NINT to function, as it uses a lot of features, such as the Internal Clock, Internal Weather System, and Enemy Discoloring.

Differences
The title, upon start-up, is the same as the final's level select menu. The actual title screen itself is similar to that of the Spaceworld 1995 build, but with a slightly different texture on the title background. It just says "64" instead of "Super Mario 64." The file select is missing the move and copy buttons, only containing the delete option, but has a new option labelled "Night." Pressing it does nothing, however. Starting the game, Mario himself is a bit floatier, and his triple jump makes him fly as if he had a Wing Cap.

The Castle
Princess Peach's Castle looks very similar to the Patent Castle, even including the cloud in the sky. The skybox is slightly different from the final, using an early version of the Whomp's Fortress skybox, rather than the ocean island of the Bob-omb Battlefield skybox. The golden design on the castle entrance is repurposed into a clock, counting the time of day using the NINT's internal clock. The skybox and terrain of the castle, as well as the whole game, can also have slight variations based on the weather. As for the inside of the castle, it bears a resemblance to the final version of the castle used in the released build of the game. The walls picture hills and clouds, which also change with the weather and time. The layout of the castle is much different however, as it still bares resemblance to the E3 or even Spaceworld 1995 layout, with primitive painting rooms and the lack of a staircase. The stairs leading up to the second floor are gone, and the hallway to Bowser in the Dark World takes its spot. In place of the top left spot, Wet-Dry World is there. Completing Bowser in the Dark World's one and only star gives you a screen saying "THE DEMO IS NOW OVER. RESET CONSOLE." in bright orange text, with no background or music. Returning to the castle after resetting the game resets all your progress.

Bob-omb Battlefield
Bob-omb Battlefield uses the early Whomp's Fortress skybox, just like the castle. The rocky pits look a bit more natural and have a flowing river coursing through. The rocky spike from the top of the early Bob-omb Battlefield is gone, however. On rainy days, there is a chance to find blue Bob-ombs and purple Goombas. Sunny days usually can result in the rare occurrence of orange Bob-ombs and Goombas. Cloudy or foggy days can result in white Bob-ombs. The Big Bob-omb fight is easier, as he takes longer to turn around completely. The Big Steelies rolling down the hill only appear near the bottom, and circle around a pit before disappearing. During the rain, the river floods and some of the level is placed underwater. During sunny days, the river dries out. Whenever it is cloudy, foggy, rainy, or stormy, Big Bob-omb will be missing. A Bob-omb Buddy will be there, telling the player this:

"The king left the mountain temporarily in our charge. Hooray...? He says he'll come back to kick our butts again, but I'm sure we'll be fine. The Big Bob-omb says that life on the mountain is hard and he wanted to go take a vacation. Here's to hoping he won't come back again."

Whomp's Fortress
Whomp's Fortress's tower is active on all missions, and a door to enter the tower is given. A crack on the wall is in place where the 1-Up secret is. The level itself seems to have a few grass spots, and the area of water is gone. Most of the sloped areas are now removed entirely, save for a balcony with a secret star, given to you by a Bob-omb Buddy for reaching the place. Every Thwomp is grey, in any sort of weather or difficulty.

Wet-Dry World
The player spawns in the town area instead of the main level, the town itself has a few minor differences, the "Church" is enterable, same with the houses, the cage used for the Vanish Cap star is gone, the star is also gone, on rainy days, the buildings are flooded, on sunny days, the level dries up and is populated by more natural enemies, like Goombas and Bob-Ombs, on stormy days, Amps appear, on foggy days, there's white fog in the level, nothing happens on cloudy days
