Welcome to SmileBASIC Source!

A community for SmileBASIC enthusiasts! SmileBASIC is a set of apps for Nintendo systems which let you program in BASIC right on your console, and share your created programs with other SmileBASIC users! It started on the Nintendo DSi as "Petit Computer", and is now available as "SmileBASIC" on Nintendo 3DS, Nintendo Wii U, and Nintendo Switch!

We're here to make it easier to find programs made by the community, and to promote your own programs! We also have a forum with extensive history, you may be able to find answers to most questions there! There's also an active discord where you can get real-time help and discuss your programs.
