Neo And Xarcade Together

hi there…i have built 2 player cp for neo and xbox…the problem is neo using only one ground for all buttons but xarcade is using seperate grounds for each group…for example it uses one ground for buttons 1,2,4,5 and one ground for up,down,left,right…so i have 4 grounds…any help is desperately needed…i have wired all grounds together…how can i use them together? thanks


Xarcade PCBs suck. They lag on everything. Mod it with Happ Competition sticks/buttons and switch the PCB to a dualshock to get a decent stick. You will then be able to use it on Xbox and Neo Geo with controller adapters.
