SMILE OS is an operating system for the SMILEBOOM engine, licensed on Nintendo 3DS. You will need a username and a password. It comes with the OS. There will be local wireless to play mini games and such. Applications are a go. If you wanna help with this, just ask.

I think somebody already made something called smile os, also you can't license games on SB

smileboom is licensed on the 3ds

I know, you can't license games you made.
