Video explaining what is this stuff around Decimeter (archive).

The decimeter shrine was removed around the 6th january 2022. It's apparation were controlled by a bot.

Deletion reason by Capypara :

Heya! Due to concerns, I have decided to tone down the meme-ness of how I used to run this server. No more icon changes and I also archived the Decimeter shrine and removed the memy roles. Please confine memy behaviour to the dumpster channels (see the role in rules-and-roles to get access).
Sorry for making people uncomfortable and I hope we'll all continue to have a great time here!

The joke is that this server used to have 8 rules so para added the emote as a joke
But then we needed a new one because of Stuff
And he also wanted the emote still
Thus

Sky Editor (the Rom Editor, aka Sky Editor version Old) is the old one that does PSMD, GTI, and Explorers. Sky Editor (the Save Editor) does Explorers abd RT.

Sky Editor DX is a rom editor for RTDX, rewritten and using very little of the old stuff.
DreamNexus is a fork of Sky Editor DX that adds new features and replaces the UI with something that can do more than edit starters. And it kinda became the main version due to my own inactivity.
