Yep.  The error occurs because the directory
`gamegrid-user-score-file-directory' (i.e. '~/.emac.d/games/' on my
system) doesn't exist.  Emacs should probably create it if it doesn't

Yes.  You shouldn't use "/tmp" literally, of course, but
`temporary-file-directory' instead.

Yes, at least one, which was why I noticed.  

The way to use `gamegrid-add-score' before the change was to supply an
absolute filename.  E.g. this was how the bundled games did it in Emacs

snake.el:(defvar snake-score-file (concat temporary-file-directory 
tetris.el:(defvar tetris-score-file (concat temporary-file-directory 

I'd strongly suspect that every non-bundled game does something similar.

Backward compatibility would be nice, if possible.  But I don't
understand the security problem in the first place, so I have no idea if
it _is_ possible.
