Gaming What Makes Demo Carts Launch on Boot?

[Scarlet]

Title pretty much says it all.

Bought a few demo carts since I like that kinda thing, and I'm wondering what makes them launch straight away? If you turn the console on with one in, it launches it straight away, and doesn't allow you to return to the Home Menu. It also powers the 3DS off straight away if you press the power button, in oppose to pulling up the standby screen.

I'm just curious is all, thanks in advance <3

By demos you mean store demos? I think that is because the store demos are not suppose to have access to the home menu since they are well demos for stores. That was a horrible explanation. I can't explain it any better though

While exploring the rsf files of .cias, I found some tags about auto-booting. Maybe the cartridge has something that causes the 3DS to enter a "Demo Mode" where the Home Menu is bypassed entirely and the Home Button becomes locked.
