Both ports are playing up. The mouse and my game controller are acting very funny. The mouse cursor is moving in ways that are simply not possible. I'm thinking I've damaged U15 or a component on its path. I've a new motherboard coming and a new Denise. I'm thinking this is the best solution for now. I'll have a look at replacing U15 and the Exxx and Cxxx components at some point in the future to see if that sorts it.
