I think an important question is whether you will be compiling / linking this
code with anything covered by the GPL, or whether you'll just be making it
available for people to use on something (Rockbox) that's GPL licensed.

So, basically, you're not allowed to get money or anything equivalent in
return for letting people use it.

Again, no "commercial gain".

I think that is neither here nor there (however I also think the answer is
"no"). The important question is not whether "Rockbox" and the developers
behind it are considered a commercial entity, but whether any commercial gain
is involved in distributing this game.

I would say that this licence is incompatible with the GPL, because it
restricts the distribution of the code (by saying you can't earn money from
doing so) whereas the GPL says you can't restrict distribution in any way, and
even explicitly states that you can earn money from GPL code (if you can find
someone willing to pay for it).
Anyway, that said, I am not a lawyer :)
Don't procrastinate - put it off until tomorrow.
Please reply to the list;
please *don't* CC me.
