thanks jimmy!

I didn't even know it doesn't support those Mega man games. That changes the balance of where I'm leaning.

I guess the other reason I wanted to get the powerpak is to try rpg's...yet another category where the carts are expensive.

I'm not too knowledgeable when it comes to all the specs and chips, but I'm assuming games like Lufia, Earthbound, BOF, Secret of Mana etc ARE compatible with the powerpak. But that thing is so damn expensive.
