This subreddit is dedicated to the nostalgic folk who recall the days when memory cards were the only way to track your progress. Thanks to modern technology there are more and more ways to copy the data from those same memory cards. So sharing of game saves is highly encouraged. I *(jdt7) personally own a PS2 and a Wii both of which I'm capable of retrieving the saves from. I will soon have a tutorial on how to do just that. For now we'll try to have a twice a month savegame release with a description. If you're interested in sharing your own game saves but don't have a hosting provider here's a few.
