GMMOS

GMMOS is a mockup username operating system by GMM with Version 1.0 released in 2019. GMM has made several changes to OS with 3 updates being posted.

This OS is now de facto obselete because GMM's channel was terminated in early August 2019. However, GMM has now made a new account since then and an Update 3.1 might be on the horizon if GMM reboots WNR and/or NROS.
