just wondering…
I’am sure a build I used before worked better for me and I have no idea which one it was. I’am using a Bluetooth adapter and two ps3 controllers with better ds3 tool.
I can not get player two to map and takes over player 1.
Better DS3 Tool will set my Controllers as XInput and auto map to an Xbox 360 mapping. Which I have set to do.
What does your User 1 & User 2 Device Index come up as? User 1 & User 2 Device Index show - Controller (Xbox 360 Wireless Receiver for Windows)
When I bind User 1 it works and then when I go to bind User 2 only User 2 Controls work.
So I’am using Scarlet Crush and still having the same issues. 
would this have anything to do with the problem?
input_driver = “dinput” input_joypad_driver = “winxinput” input_device_p1 = “0” input_player1_joypad_index = “0” input_libretro_device_p1 = “5” input_player1_analog_dpad_mode = “0” input_device_p2 = “0” input_player2_joypad_index = “1” input_libretro_device_p2 = “5” input_player2_analog_dpad_mode = “0”
If this helps at all.
i tried with disabling autoconfig. I’ve tried these builds RetroArch_1.0.0.3-beta, RetroArch-v1.0.0.2-32bit, 2015-02-10_RetroArch.
Thanks for you time and help. i know you probably have better things to do,
so I have tried to change the “5” to “1”
and still the same thing…
everytime i got into retroarch my player 1 device index ends up being xinput controller player 2.
input_device_p1 = “0” input_player1_joypad_index = “0” input_libretro_device_p1 = “5” input_player1_analog_dpad_mode = “0” input_device_p2 = “0” input_player2_joypad_index = “1” input_libretro_device_p2 = “5” input_player2_analog_dpad_mode = “0”
i don’t know why my device’s are always setting to “5”
also on window 8.1 i don’t know what other info i could give here…
I’m gonna do so digging and see if it was the stupid motioninjoy drivers or something giving me the problem. I’ve I come up with something i’ll post it. if not I might just do a fresh os install.
Sorry for taking up your time and thanks for the help anyways. 
k. So I can get two controllers two work in nestopia core.
I have to bind both my controllers with bind default all. Which before I was always binding my controllers manually with bind all.
So now… My player 1 controller works as Player 2 and Player 2 controller works as Player 1.
and
When I do bind my controllers manually with bind all, I still have the problem with only one controller working and it ends up being the last controller I bind with. I don’t know how many endless hours I’ve been at this… lol.
k now if I switch back to dinput and bind all manually it all works. wop wop.
