Went back to work on the Super Game Boy cover.
There's a few variations, so here's some previews which show them off. Let me know which combination of things you prefer, and if you see anything that needs fixing.
Grey front text, and information bubbles on the screen shots on the back.

Blue front text, no bubbles.

And, a first for me, an NTSC version.
Bubbles.

No bubbles.

EDIT: Just realised I'll also need to edit the text on the back of the NTSC ones, to "fix" the spelling of 'colour' and 'maximise'.
