noname Mame roaming on me

[ncflagg]

I am using Noname Mame .83. I have a cab project going utilizing a gamepad and ps/2 mouse as the controls. If I run a trackball game like Centipede, the cursor/ship moves up and to the left slowly. If I disable the gamepad the cursor stops drifting but the gamepad must be on because I use it as my P1 start and P2 start buttons. Mame32 .84 in the same configuration does not do this. Has anyone seen this behavior before?

Your game pad is not perfectly centered.  Start a game, tab, "input (general)", player 1, and unmap your gamepad from the trackball inputs (IOW, remap the same as the defaults, except don't include the gamepad directions).  Might want to do the same for the dial type (spinners) too.

That sounds like something to try. How do I set an input as mouse x or y axis? And what file is that stored in?

Same as normal remaps: start game, tab, select either "input..." menu item, select what you want to remap with enter, spin/move spinner/mouse fast but not too fast, wait, (repeat enter - input input - enter as needed).  The one thing in mame often gets both the X and Y axes.   You can either move off the item you're remapping, move back one and try again, or edit the file with a text file after you've changed it from the default.

The files are in the cfg folder in the mame folder.  If the changes are in "Input (general", it's the default.cfg file, otherwise it's the gamename.cfg file.  You can edit with any text editor (notepad works), or a good xml editor (an overkill IMO, though).
