It has a few changes just for the 3DS and to make it more like modern programming languages. It also has built-in sprite and background tile commands. (For a full list of new commands, look at the SmileBASIC website)
It's pretty powerful and it's worth the $10.
The MIC commands already let you do that. The DLC just lets you apply effects in real time and stuff like that. I'll post some example code in a minute.
I might still make the EX8TECHDEMO-style parts and quiz parts, just not huge lessons, those are going to be on YouTube. I'm currently scripting the first video now. I just need a decent camera. The iPad 2's is horrible.
It's a really annoying twitter bot that always replies with this kind of thing. "[tweet subject] sounds great, but we need more information about the NX."
It transmits data using the 3DS MIC, so you'll need to get your 3DS really close to your PC speaker and microphone and pray that nothing goes wrong for it to work. There's a Petit Modem app for PC, too. You'll need to use them together and select the same options for it to work.
I really wish it was as easy as you said, but SmileBASIC can't do that…
WHAT IS GOING ON ANYMORE
Seriously, what happened to A%? It's supposed to be an array, but it's not?
DEF STR_TO_ARR S$ OUT A%[]
WHILE LEN(S$)!=LEN(A%)
PUSH A%,ASC(S$[LEN(A%)-1])
WEND
S$=""
