Here's some more.

Anything can be changed on them, these are only mockups. I did 20x20 
pixels for the disks. I'll try a joystick later, and perhaps try and 
think of some more ideas - I'm not sure what screams "old videogame" 
that is recognisable though (any ideas?). I do agree the swirl on the 
label looks better then a P and the object covering the swirl so I 
didn't bother with that for the 5.25" disks.
