2 psx controllers .. do they share same ground or different ones?

[Negativecreep0]

can two psx controllers share the same ground going into a db25 plug or do i have to split them up???
thanks

you need to split them up.

[Negativecreep0]

so if each controller is going to a p360 i assume they need seperate +5 connections too?


damn to many connections to fit 2 psx in one db25 cable, 6 buttons + start + 4 directions + ground + +5v = 13 connections for each control = 26 points for 2 controls.......


damn

26 is perfect if you use the (unshielded) groundcable in a db25 cable, I did it with my PS2 hack...

[Negativecreep0]

can you elaborate on that where is this 26th cable? and did you use 2 psx controls to one db25 cable???

[Negativecreep0]

since both player one controls and player two controls on the arcade stick are all connected with daisy chains for its ground then won't ps1 controller and ps2 controller grounds come in contact anyway?

I used a separate ground for each pad.
Up, Down, Left, Right, Triangle, Square, Circle, Cross, L1, L2, start & ground = 13 functions/ wires

Most db25 (printer-extention) cables have 25 shielded and color-coded wires PLUS 1 bare ground-wire going from plug to plug, meaning you have (25 + 1 =) 26 cables to use.
