The Personalised Computer

The Personalised Computer is a name dubbed for the PC that was used to create the Personalisation AI. It is believed to have run on an operating system akin to the QNX system, but it had a slightly modified GUI and a heavily modified kernel.

The Computer contains system information for the AI and its true purpose, of which is said to be locked with a password. The password is unknown, but the name is thought to be in the nature of "info.cab".

The Computer is said to be in The Nintendo™ Headquarters of Japan, but realistically it is most likely destroyed or locked somewhere.

Although no screenshot of the PC itself or the GUI has ever been found or taken, it is claimed that it is akin to a Silicon Graphics™ Indigo.

Speculation
It is alleged to be part of an internal server for Nintendo™ that specialises in creating Super Mario 64 and its AI. Nintendo™ employees most likely used this workstation to develop the AI.

Other theories claim that the system was actually created to develop the original Stop n’ Swop mechanic, but these claims have not been 100% proven, although there is further speculation about a certain mechanic being developed on a “special” workstation.
