This would be a relatively easy task for someone to work on. We have a new library libgames-support which scores player names along with scores. The task would be to remove five-or-more's custom scores handling and use libgames-support instead. There is a wip/libgames-support branch of gnome-robots that could serve as an example.

There is one problem: currently libgames-support is not able to import scores. It would be nice to make this transition without deleting all the users' currently saved scores. (Imported scores would just be given the name of the current user at time of import.)

The initial limitation of libgames-scores not being able to import previous scores seems to be gone, as the library does have an importer mechanism implemented since february 2016. Anyone interested is welcome to jump on the task, patches will be reviewed in a timely manner.

Use libgnome-games-support for scores

I have also checked to see if old scores are being imported and it seems to be working fine. Please let me know should I change anything in the current patch. Thank you.

Thanks, this looks fine, took me a while to merge with the current split code, but it was not something very tricky. The only thing missing (which I found during merging) is that as gnome-games-support also provides games-gridframe, you could have dropped those files, but I have done that, it is a minor annoyance. Pushed your changes to master.

This problem has been fixed in the unstable development version. The fix will be available in the next major software release. You may need to upgrade your Linux distribution to obtain that newer version.
