I can't wait until someone smarter than me makes external editing tools for SmileBASIC. Then, I won't have to struggle making sprites, and we'll all be able to share copyrighted material *evil grin*

I have no clue why I was forced to use a screenshot here, but whatev's

You can use petitmodem to import sprites from your PC.

but the thing is you need a $20.00 microphone splitter to transfer data quickly

I had no clue that was even a thing. Sounds interesting nonetheless!

I've had some luck just aiming my PC headset's mic at the 3DS speaker...and I also got a four-conductor cable and hooked it up that way, too. It works but it's not exactly foolproof!
