I'm not going to explain adb as many tutorials exist. Before you do anything pull the ini file and make a copy in a safe place. Also keep a copy handy to edit it. As you add games you push the a26 rom and PNG to the atari folder, then you go into the ini and add the game info at the bottom, be sure to leave a space between games and read the ini to see the format to use, it starts with [rom name] and then has some defining traits below it. You can copy one and paste it, simply changing the info to match the new rom added. Save the ini and push it back to the atgames folder, rom and PNG to Atari folder, reset the system and it will show up. There are several variations for cords also, I used a ten foot cord and have it retract into the console, you could buy a USB extension cord and remove the male end, solder those wires and add a hole in the case for the female USB as an example. If you want it to read a flash drive you will need the 5v wire and I haven't tried that. I made the hole for my USB cord in the rear by heating a Phillips head screwdriver driver and pushing it through the plastic then pulling it back out quickly to ensure any excess plastic was on the inside, then used an blade to trim the excess plastic away. You will notice it ends up sitting the same as the power cable. Photos below. Hope this helps someone out there. Also, I'd like to note I don't advocate piracy, I am however an Atari fan and several big games got left out, and since I own the carts I decided I'd add them to my flashback so I could preserve the original copies. I forgot, you need to use this command: adb shell mount -o rw,remount,rw /system to make the system files writeable.
