It is running incredibly well for a beta version! Sound is great.

Is there a way to hide the virtual keyboard? While great for non-DCkeyboard users, it's a little annoying to play with it...

Yes, you need the roms folder. The documentation says they can be in the root, but it didn?t work for me (that?s why the old Dreamsnes rom discs doesn?t work making it seems "unswapable", I guess).
