Game Genie had a thicker circuit board than a game cart, to get a good connection in the frontloaders. The toploader’s cart slot is pretty tight, to get a good connection. Combine these, and it feels like the cart slot is going to pull off of the circuit board before the Game Genie lets loose. Everdrive/Powerpak would work fine.

Galoob offered an adapter for the toploaders but they are extremely rare.
