GameBoy Color (US): Robopon Sun Version

[UncleBob]

Here's an oddball request for an oddball game.  Found this at a used game store - looking at the odd cartridge, I half thought it was some kind of bootleg.

Thinking "What the heck?" and that it'd give me an excuse to play with my new toy (case ended up pretty easy to modify, but I expected it to be) I picked it up.  Sadly, there's no cover here on TCP!  I'm looking to get the cover art, but I've failed many times before trying to do this... so if anyone out there is any help, that'd be great!
