You can't copy your games directly to the SD card from your Windows system. What you're seeing is just the boot partition, there is 2nd Linux partition on the SD card which is not readable by Windows - this is where the actual OS is installed. To transfer your games over use one of the methods supported - see the documentation.

@Clyde Wasn't aware of that tool. Cheers.

@BuZz Thank you sir. That helps a lot.

@drb

I created an account to say thanks and to also say I had better luck using "Rufus" to perform the iso to usb step.

That ISO to USB tool just didn't want to work for me.

Gparted was straight forward and I was able to resize my partition of my img so it would fit on another card.

Thanks again!!!

I found the issue was with my USB to SD adapter. The image did contain partitions and windows detected a new USB storage device, halting the write operation. I had no issue when writing to SD on my laptop using a standard SD slot. Image is clean, well configured right out of the gate.

@ceruleansoul Here's how I successfully installed Retropie:

Made sure I have a formatted SD card to FAT32. Follow the download instruction and installation for P2/P3 from this site:
