I’m struggling too

Pi Model: 2 B
RetroPie Version Used: 3.0.0 Beta 2
Built From: SD Image
USB Devices connected: Keyboard

Guide used: https://www.petrockblock.com/2014/12/29/controlblock-power-switch-and-io-for-the-raspberry-pi/#Using_SNES_Controllers_with_the_ControlBlock

built the controlblock last night. Plugged it all in. emulationstation saying there are 2 controllers connected but the snes controllers are not responding at all.

Tried to follow the steps provided for dotarj

Here is a pic of my setup
controlblock 2 snes

i2c was next

went into the ControlBlockService folder

sudo make uninstallservice

pi@retropie ~/ControlBlockService $ sudo i2cdetect -y 0
Error: Could not open file <code>/dev/i2c-0' or</code>/dev/i2c/0': No such file or directory
pi@retropie ~/ControlBlockService $ sudo i2cdetect -y 1

I tried a fresh image still having exactly the same issue.

Do i need to swap GND and VCC?
