I'm using the No$GBA Emulator, but every time I load a game like Picross DS, the game will load and all that good stuff, but than it will say it can't access the save data. Why is this? Shouldn't it just make one on it's own?
I found out you can use Demos and play them (The ones from the Wi-Fi Center in Walmart) by downloading them. Why can you do this but not play the regular ones? Does it have to do with the format of something?
