Well, I haven't quite finished up the Sonic 2 cover, but I think the template is pretty much ready. There isn't much to it: a spine logo, some text on the front and back, and the copyright/contact/UPC area.

I also left the "Sonic the Hedgehog 2 1992 SEGA" part on the back so people can change it or leave it off completely. You can also change the color of all the text to whatever is appropriate for that cover.
I'm also uploading a folder of images I've collected. It contains reference photos I could find for some of the LCD games' packaging. If anyone wants to take a try at some of those, you're welcome to.

After Sonic 2, I'm going to try my hand another Tiger Electronic LCD device. Though not technically a game, I believe it should fit in a UGC and I personally think it warrants a corresponding cover:
