I was wondering can we upload for example F2nd,F,2nd,extend beat maps to the site ?
i know you cant upload Real AC beats maps but i was wondering what about beat maps from the other diva games?

It's same as AC versions, so no, you can't. Because those aren't your work completely, it's only a copy of official notechart.
You can recreate those maps, but you should upload them somewhere else (Mega, dropbox etc.).

Ah ok, thanks any way

was thinking to creat some note charts from Dreamy teather

Oh well..

Actually u can but u need scripts for F2 F hold notes but as of now u can't since there are no script of those. U can make the arrow notes but not the hold. SO in short, no

welp i can always replace the arrow note with normal notes or slider ^^
