Weird. Multibutton works on Vice but not on a real C64 with Ultimate2+. I checked on testers and other games that support the second Fire. Both on 8580 and ArmSID. Rocky does not respond to the second button. Other games/programs (e.g. second fire in Briley Witch Chronicles) have no problem. The mouse works in Geos. Does anyone have this problem on a real C64 with U2+?
