Another strong batch here. I don't know the game but my favorite here was the cover of Trouble Shooter (?) the Vic Tokai game.
Dragon's Revenge is also pretty nice with googly eyes.
Hah yeah that Bubsy just works, could have been legit.
That Jim Power one isn't bad either, and that game is getting a stellar re-release here under a licensed publishing agreement via Piko Interactive for multiple formats this year. It's a cool game, a rebranded Buck Rogers game no less. He's even got some versions to release that were canceled back in the day if I remember right.
