No plans for now. There are game-specific configurations we store in there if you need it. Yes it creates a truck load of files, but most of the time it shouldn't bother you until you start looking at the folders in File Explorer, but even so, you could still sort the files by type, and remove stuff you don't need easily . Interesting... I'm fixing some stuff in Snes9x for 3DS now. Will have a look at the coin thingy when I get some time. As for the screen corruption, it could be a mapper issue. Not sure if it can be fixed, but I will have a look at it again later.
