Hell yes you should be able to use trackball or joystick. If a game is originally played with trackball, of course you play it with mouse or trackball. Isn't it allmost cheating when someone uses keaboard in trackball game? -(answering myself) In my opinion "original" controls seem to have best effect, so use anything you want except autofire(you are welcome try to beat my Marble Madness score with any controlling method you like...). I bought a trackball for Marble and haven't regretted it a single moment-It really isn't so expensive and I use it as a spinner also...furthermore Marble is ten times more fun with a trackball.(posted 9573 days ago)Emulation for trackball is perfect, problem is to find right analog- settings. If sensitivity is TOO HIGH marble seems to stop or go wrong direction, when rolling fast. You should experiment with analog settings, changing sensitivity and that other prosentage value (something like delta x prosentage). Normally I use final-versions for recording, and trackball works just fine. I've noticed that later versions analog settings look different compared to older ones, but they work just the same. It's my lazyness,that makes me still use M35b2 for marble-since I found right settings with that version and don't want to experiment for few ours with later versions.
