I may want to remove the two unknown chips which I suspect are some type of PLD's and try to determine their configuration which would make the task easier, so I don't want to mess with your board but thanks for the offer.

One thing you might try is seeing if you can gently peel up the labels without damaging them (on the two chips with labels) and read the part numbers off the chips.

The edge connector connection seem to be supposed to go in some IC labeled SP720AP, but those chip aren't there. Those chips seem to have been hand-removed, this is why I wanted to check if there was any game hided on the cart, but I guess it has nothing on it. Very weird cart indeed.

When I insert it in a genesis unit, nothing come up, so the cart must be empty, but when I opened it, I found out that there is no pins from the cart connector that go anywhere except for the ground if I remember well. I have some Hi-Res pic of the gut of the cart if you are interested in it.
