Well, I've started playing Dark Souls 2 and thought it controlled amazingly well with the mouse in right trackpad. The only problem is that it's impossible to switch targets. Mouse Joystick solves the issue, and although it's not as good as the mouse emulation, it's still better than moving the camera with an analog stick.
You can set a mode switch on the right pad to convert it from Mouse to D-Pad, activated by right pad click. Then on that "lower" D-Pad mode, bind keyboard O to Up/Down, and keyboard J/L to Left Right, and you'll be able to toggle targeting and cycle targets by clicking quadrants of your right pad, while maintaining mouse accuracy.
