Retroarch for pc controller config help

Hello all! I am new to using retroarch and i am having a hell of a time configuring my xbox 360 wireless receiver to work with retroarch. I can get it to work with just one controller but not 2. Ex when playing snes and i start a 2 player game player 1 will move and do everything just fine. Player 2 will not move at all. I go into the input options and player to #2. I then change device to xinput controller (player 2). Thinking that would fix the issue but it doesnt. Is there something I am missing i need to setup first. In windows device settings it registers both my controllers as individual devices and i can go into the properties for each and when i click a button it only registers for one device. Hopefully someone can clear this up for me and maybe this will help someone down the road later on. Thank you for any help.

Does it work if you set up the bindings manually for the 2nd player?

it does for sega genesis but not for snes9x

Are you using an old version of the library, by chance? I seem to remember 2+ player input mapping to be missing from snes9x awhile back, but it’s hooked up in current git and has been for some time.

I do believe so. I dl the RetroArch megapack (20131013) (64-bit) from the site and i am running x64 win7.
