No pirating.
They aren't? How not?
You aren't getting full games for free, you are just running homemade games that are released as free software. Taking a pirated game and using a loader to run it would be piracy, but running homebrew using one isn't.
Why do people homebrew mostly on nintendo consoles?Because there is nothing else to do with them
I don't feel comfortable downloading these, I don't want to get capped in the rear by cops and sent to court.
So what do you actually need to run Homebrew games? Can you do it just from a SD card on a DSi?
