I spent a couple of hours trying to get my new trackball and spinner working last night. They worked as "mouse" devices in windows immediately after plugging in the minipac. However, mame wouldn't recognize them, and the config for the game was getting screwed up as I tried to use the tabbed menu controller setup to add them.
Eventually after lots of web searching and reading I found a file "mame.ini" to download that wasn't in my mame directory before, and edited the setting "mouse" from 0 to 1. (trackball is still set to "keyboard" instead of "mouse" but the comments I was reading suggested that was fine?) Now I have to work on tweaking sensitivities.
Anyhow, I'd like to edit the individual <game>.cfg files manually, but until you start changing defaults these files are basically empty. Can anyone point me to the best reference/example/tutorial page for doing this, listing and explaining all the .cfg file options? Thanks!
