Thank you for the answer. Too bad it's not already contained in the kit since recoil-function is something that to me makes the arcade-feel come back.
I've been looking at EMS topgun III as an option too and I'm wondering if someone has managed to make it to work for 2 players in MAME?
It's cheapish and it has some really mixed reviews so I would like to hear if someone has used it with success.
Or if there's an option somewhere to choose those recoil-kits as pre-installed as well. It would be good.
