Yup, it's a Megason 3, I really like it because of the design and the fact it has those slots on the sides to put the pads!
Thanks for bumping this. That's an impressive lot of stuff you have there. I like the GameKing box, never saw the packaging before.
There are 2 different boxes AFAIK, but this one's my favorite! http://www.bripro.com/low/gameking/index.php?page=compare
