A third question that I have is by adjusting the speed sensitivity on the mouse/trackball control in AtomicManager, it still seems to stick a bit...no matter what speed it's set to.
I'm going to check that. What you mean bu it seems to "stick" a bit?
Up to this point, I have been using Mamewah. In that FE, you can literally spin the trackball fast and the game list would fly (read: move very fast) through the list of games.
Ok, i checked. Here is how to proceed.
To increase the sensitivity of your trackball move the "spinner/Trackball/mouse" sensitivity slide to the
LEFT.
That won't change the speed of the gamelist scrolling but i changes the moment of the move detection. Said , if you rotate the trackball with an angle of 10° it will be considered as a "move" , if you change that parameter you can make it detect an angle of 5° . I don't know if i'm reallty clear here...

In fact it is a kind of "reaction" time.
Then to speed up the scrolling in the list.
-check "advanced options" check box on the "general tab"
-go on the "Advanced Tab"
-go on the Atomic <0.15 tab (even if you are using Atomic 0.18 or more)
-Decrease the "key repeat delay" , put as exemple 10 instead of 100.
Save and close. And it should be really faster.
By combining both parameters you should be able to set the trackball behavoir as you want.
But i'm not sure it will be as good as MameWah.
I have to improve that kind of setting because it is not so obvious...

I hope it helps.
It's by far the best on the "market" in my opinion. And these docs only improve it.
Thanks a lot.
