40 MB is huge for a Genesis cart, If Sonic 3 and Knuckles were together, the cart would have been 38 MB. Home-brew games also cost quite a bit. They do need to print boxes, manuals, and be able to afford the cost to make this game. I mean, Bound High on Virtual Boy(I really want to get it) is $75 PLUS shipping! Hopefully the developers will be able to make a profit.
