1. Games purchased digitally from the e shop: do you get a PIN # for Club Nintendo coins? 2. How large are the file sizes, insanely huge? 1GB+? 3. Where are the games stored? Internally in the 3DS or on the SD card? 3-a. If they're stored and run from the SD card, does the SD card itself need to be a certain read speed to ensure proper game performance? 4. Deleting and re-downloading: is this a simple process? (no experience with buying on the e-shop, bear with me) 5. Transfer of digitally purchased games to another system. Possible?
