@TheRealSmilebit interesting! What kind of dremel router bit did you use to drill the square hole for the trackball? I’d like to do install a trackball on my controller panel, but ist is so thin, I don’t want to mess it up.

Thanks

Have you been able to use spinner & trackball at the same time? or do you need to change the mouse index in game each time??

@jero123 Just a router bit. Not sure if there is any particular size for the Dremel...think it is just called a router bit. And yes...have to be carefully. I try only route out a 1/4" of an inch to make sure there is enough to hold it in place...just if you decide to do it, get some scrap wood and practice on it before doing on your control panel.

@ESMITH1120 No have to change the mouse index. Retroarch sometimes does not save, so have to manually edit the config file for the roms that use the spinner. The trackball is set to index 0, so that is the default. However any game that needs the spinner, which is index 2, I have to edit the config file. But only have to edit once and the setting stay.

@TheRealSmilebit Ok, and just one more question, what holesaw size did you use for the trackball? (2 1/8 inch?)

Thanks!
