I agree with a lot of people that this list is almost completely "shovelware."
However, think about the people who DO buy these games, one example being parents for their children. In all seriousness, I can see a parent buying a flashcard for a child due to the prospect of saving a lot of money (albeit not really caring about the legal consequences). I have seen a few children with r4 clones myself (and one with a Slot-2 device), thus confirming my point.
(Besides, I can see a few nefarious people who want to pirate these game specifically to run the shovelware-makers out of business...)
In all seriousness, I hope that I can dump at least one of these games. I do not want to be in this community without contributing anything.
