Universal Systems Austria

Universal Systems Austria, also known in German (the main language of Austria) as Universal Systeme Österreich, is a now-defunct brand that operated in Salzbrug, Austria. The purpose of the brand was to bring foreign-based games into Austria, albeit most of these products came from Germany due to physical and linguistical proximity.

The brand is known in the personalisation community for a supposed 'Austrian' version of Super Mario 64 for the Nintendo 64.

Anomalies
Universal Systems Austria, in 1999, released Super Mario 64 Österreich for Austrian versions of the Nintendo 64. This copy, although relatively unknown globally, allegedly contains features that were not present in other versions of the games.

One of these features include an alleged custom outfit for Mario that could be unlocked in an undocumented level that was supposedly special to this version of the game. It took on the appearance of a stereotypical Austrian outfit whilst, upon unlocking it in the aforementioned level, a text would pop up. According to one or two sources, the text may have said:

"Herzlichen Glückwunsch, Mario! Du hast den österreichischen Modus erfolgreich freigeschaltet!

Jetzt kannst du Spezialfähigkeiten ausführen, die du vorher nicht ausführen konntest.

Dieses praktische Outfit soll dich durch deine Zeit in Wien begleiten. Genieße den Rest deines Tages!"

(SUPPOSED) ENGLISH TRANSLATION:

"Congratulations, Mario! You successfully have unlocked Austrian mode!

Now you can perform special powers that you were unable to perform beforehand.

This handy outfit shall guide you in your time in Vienna. Enjoy the rest of your day!"

The 'special powers' in question are mostly unknown, though sources guess that it was likely related to Austrian culture. More percuilar though, the text mentions that the outfit will guide the player in their 'time in Vienna'. Sources believe that there may have been a specific level that would take Mario to the city of Vienna within Super Mario 64.
