I'm hoping that was sarcasm. X.x
If not, would you swear by your honour that you own all said games in the flashcard?
Seriously... People that actually use that excuse are saying complete and utter bullshit!
When I used to pirate I certainly didn't own the games I downloaded. As for internal memory... My 3DS has a 32GB card and I have no issues with space, currently I have over 20 digital 3DS games... although I prefer carrying buying retail, so I always carry two of those Nintendo 3DS cases for 18 cartridges that you could get with stars on their website
No, I sell all my legit games when I have them backed-up. I see no need to keep a hardcopy anymore. I sell them for more 32GB SD cards. I'm not against piracy at all, I just don't find piracy worth it if you have to play with 1 game per card, like the current Gateway setup. Multirom might sell me on it though, once these brickings are finished with.
