Alrighty,I'll introduce myself.I'm a former NSLUCer named Catro/Caragh.For years people have said they'd make a fanmade Miiverse game.Well I'm new to SB[as in,just bought the game]and I'd like help with spriting and programming and such.
If you want to learn how to use smilebasic, then you should visit smilebasicsource.com . There are tutorials to make games and other tools that you can use to make sprites, music and improve your code.
Also, you should start with something simple. Try to understand the program EX[1-7] from the folder sys and then start a small project.
