DefaultioWow, already with that homebrew in the end. Wonder if SBHax will be possible....
It (probably) doesn't. That's the point. Just because we can crash the software doesn't mean we can force the 3DS to run our code.

CrashSB
CrashSB is a program featuring a bug I discoverd.
What it does
It crashes SB (this also means unsaved data will be lost, so please save everything before doing this. YOU HAVE BEEN WARNED!). Then the 3DS error handler comes in and takes you back to the home menu and then restarts the system.
How to use it
This only works in edit mode. After running the program, the user will be prompted to enter CLEAR in direct mode. After that, They have to enter CRASH to crash SB.
How it works
It is pretty simple, yet confusing. This program defines three variables and a function called CRASH. Once the user clears the RAM and the executes the function, SmileBASIC doesn't know what to do and crashes. The confusing part is that normally when a variable is not defined, it will simply give an undifined variable error. CLEAR only works in direct mode, so that's why the user needs to type it in manually.
I discovered this glitch while working on a CHIP-8 intepreter.
Can this be exploited?
Turns out people are exploiting other bugs to launch the homebrew channel.
Fixed in 3.3.2.

It's rather unlikely that this crash is vulnerable. I'll try to come up with a decent explanation with my very little knowledge (THIS MIGHT BE WRONG, WARNING)
Virtually every exploit on the 3DS relies on stack-smashes or similar techniques to write executable code to the XN (eXecute Never) memory. Normally this memory area is blacklisted so you can't write to it or something and blah blah the program counter jumps into free memory to execute a deployed something or other or something.
somebody check my work

Even if homebrew is possible in SmileBASIC, I think we should wait until it's released in Europe to announce it. Nintendo will surely force SmileBoom to patch SmileBASIC if a homebrew exploit is discovered, and that will delay the release of the European version even more.
tl;dr
Don't ruin SmileBASIC for others by being impatient.

JustGreat you have a point there. I don't wanna ruin it for fellow Europeans (or anyone in the world) and I'm not going to research this glitch, nor was it my intention. I just wanted to mention that crazy stuff has happened with glitches and exploits on both the DSi and 3DS.

Bleh, I'm sure we'll see PetitHax sometime.

Petit Hax sounds stupid.... SmileHax is better. But yeah, no way to know if homebrew is possible or not until we research... after the european release.
I don't know. I might delete this program, because it's grabbing all attention.

Jacklack3Hai! And i talked on GBATemp about this, they say it has to fully crash and not just crash out. So no.
maybe we can run teh program in a loop to destroy the 3ds.

No.
The first time through the loop, it would crash and the loop would stop.
Wait, doesn't BrowserHax "crash out"?
Maybe you could transfer it to a thread or resource.

I think that only happens when it fails
(90% of the time)
PRINT "GET SHREKT M7"*99999
You'll get enough bricks to keep the big bad wolf away
I don't know but if people like things that crash I can make a program that crashes itself whenever you do anything. I think I'll call it "Crash Course"
to get revenge on my apalachian enemies.
