Never Released Operating Systems: Episode 6 - Luigi2012SM64 

NROS 7 is in the making! :)

0:08 The Siiimpsooons !

Sorry it's short, but I needed to get this out sooner rather than later.

Yes! Old Windows NT 6.0 shutdown sound!

CommanDOS-64 (1986)

Now that Luigi2012SM64 is back, Mr. Splatoon could have another incentive to make it, so there's one less excuse not to do it.

Idea: JupiterOS 1.0 (1996; use Windows NT4 sounds)

Minderia OS (Quality Blue Edition) (2008-2017) (Use Minderia OS With Windows 11.1 Sounds) Three XP (2100-Minderia's Year) (Use Windows 11.1 Sounds)

HackOS 1.0 (2005) HackOS Plus (2008) HackOS 2.1 Alpha 1 (2010) HackOS 90 (1990) OS/3 1.0 (2009) WinIBM (2136) Macwin X (2938)
