Huh, what was that? I couldn't hear you, I was having too much fun on a better smilebasic website called smilebasicsource. Also, it really isn't a glitch, its just that the copy label didn't reach all the way to the end of the screen... lel.
Ninty? Just say nintendo. Also Its not pirating unless you do that type of stuff... Homebrew only makes applications/programs much easier to use. Like smileBASIC's SmileBasic File Manager. You can transfer files from PC to SB and vice versa! Homebrew is useful if you make it to.
Welp, you can't do it on the latest update anyways.... Also with the basic homebrew you can't do anything bad to your 3ds. Duh. So just change the sprites and background, its not that difficult.
You can just use SBFM or smileBasic file manager for homebrew. It's way better than petit modem and there's no sound and its simple to do! To know where to find this, go to smileBasicsource.
Hm another os. External, you mean other software packs from games and tools and such. Hope you'll actually be able to do it and upload it if it exceeds 4096 mb/kb. Also you said that some elements weren't yours, so you stole them. And then you said don't steal. That's the irony.
