I've slightly changed up the format since EBDX isn't (officially) available for 21.1 and tried to port over some broken scripts. I'll port them to plugins in the future, but otherwise this is for people struggling to access the old stuff thanks to Relic Castle going down.
I've also taken the liberty of zipping the files to make it a smaller download and put notes on some things, as well as updated some things so they don't conflict with each other because it was bugging me. As always, feel free to send a message or leave a reply to the resource with any issues or requests. New link so the old one is still backed up in case I've missed something while cleaning. Good luck with game making and whatnot, next time I'll include a script I wrote for adding multiple mega forms to the same item (think gendered megas, randomized mega evos, regional megas (alolan form -> alolan mega) and even a special mega form for a shiny.)
