Is it possible to import your own sound effects and/or music into Makecode Arcade?
I do not believe so. Sorry.
yes, it is possible as you can see from this conversation: We used rtttl ringtones. If you convert your sounds into ringtone and then import to Arcade. It will take some work to do this. How do i convert this ringtone into rtttl file for Arcade? - #7 by frank_schmidt
Thanks, I’ll try it
