Hello!

I currently have installed the RetroPieImage_Ver2.3 on my B+ Pi, I have expanded the memory and have mapped my GPIO controllers using this install guide:
https://github.com/digitalLumberjack/mk_arcade_joystick_rpi

mkdir mkjoystick
cd mkjoystick
wget https://github.com/digitalLumberjack/mk_arcade_joystick_rpi/releases/download/0.1.1/install.sh

sudo sh ./install.sh

sudo modprobe mk_arcade_joystick_rpi map=1,2

I then tested with:

jstest /dev/input/js0

and:

jstest /dev/input/js1

and had great results, both controllers gave me this result:

Up-Axis1
Down-Axis1
Left-Axis0
Right-Axis0
button1-0
button2-1
button3-2
button4-3
button5-4
button6-5

I then opened /etc/modules:

sudo nano /etc/modules

and added the line to load the driver:

mk_arcade_joystick_rpi map=1,2

Saved and rebooted. I am now able to use both home made controllers to navigate emulationstation after setting them up in ES BUT I can not seem to figure out how to get them to work with the ROM’s. I have tried hitting F1 when in game, no menu pops up. I have gone into startx GUI and used file manager to view all of the files including the hidden ones and I can not find any evidence of retroarch anywhere in the folders or .cfg files. I have been reading and posting at raspberry.org forums (over 80 posts) to try and get some help on fixing my issue to no avail so I though I would migrate over here and see if any of you good people could lend a hand. My project arcade is now complete with the exception of this issue, here is a few pictures of it:

Any help would greatly be appreciated! I have been working 8 hours a day for the last 2 weeks trying to resolve this and am about to pull my hair out after spending over 600.00 on components and over 140 hours hand fabricating the RetroPie off grid box.
