Hey everyone. I've been adding random people on this thread but I thought I might as well make a post as well. My FC is 0688 - 5289 - 3509. I like to play SFIV and Mario Kart 7!
1. Supercard DSTWO shows up as "Alex Rider - Stormbreaker" on your activity log.
2. You can just format your 3DS system memory and all activity log data goes away.
I don't see what the problem is...
