Thanks, Garwil. That joystick ID app seems pretty keen, but I know MAME distinguishes between mice & joysticks. My old Act-Labs light guns were mice to MAME, as are my 2 spinners. The absence of the 2 Act-Labs guns (mice) bumped my spinner mouse IDs by 2 spots.
I managed to recover my mouse IDs & don't have to go through every spinner game & reconfigure them. w00t!
Here's what I did:
1 - shutdown
2 - unplug 2 spinners & plug in 2 guns (LCD TopGun II)
3 - boot
4 - shutdown
5 - plug in 2 spinners
6 - boot
Fixed! Spinner game that have the default assignments (per my "Input (General)" settings) as well as spinner games that I've over-ridden (Discs of Tron for example), are still good.
I imagine that I probably over-complicated this & put a few too many steps in there, but hey, it works now & if it ain't broke, I ain't gonna mess with it!
Thanks,
