It is already altered.
This string-compare-code is taken from model-config.js

        compareStrings: function(a, b) {
                if (a === b) {
                        return 0;
                }
                return a > b ? 1 : -1;
        }

I suppose this was done to enable proper sorting of cyrillic titles & authors.
Simply changing

compareStrings: function(a.toUpperCase(), b.toUpperCase())

, will work for standard roman-style titles, but will break the functionality for cyrillic, as toUpperCase() will fail to return the proper uppercase character.
I think I remember that boroda (porkupan) has set up a special toUpperCase function covering cyrillic in his firmware. Maybe we can lend this code and put it in.
For strictly western-style author/title just try to use toUpperCase() and build your own installer/ your own beta-test-pack.

This may or may not be related to issue #128 on the project-page.
