But there’s a problem. See, AT Games elected to go with wireless controllers, while they handle well and have the more popular six-button Genesis layout, they’ve got some big problems that ruin the Flashback. First, the controllers require two AAA batteries to run and accessing the slot for the batteries requires a screwdriver. Second, and far worse, the controllers don’t work consistently. In my testing, it was always a tossup whether pressing a button would actually result in a corresponding action on screen. The Start and the C button were both pretty trustworthy, but every other button required repeated key smashes or brief and excruciating pauses.
