Adding Games to Atgames Genesis Flashback HD





Introduction: Adding Games to Atgames Genesis Flashback HD

This will just be a quick walkthrough of how to add games to your Atgames Genesis Flashback HD. If you don't know what you are doing and aren't careful you can completely brick your unit as this instructable requires modification of a sensitive area of the Atgames Genesis Flashback HD (called just Flashback from here on out). That said I cannot be held responsible for any damage you may cause, this is at your own risk.

Tools you need:

Philips Screwdriver

a computer that has a working adb setup (android bridge, I will not cover installing this here, you will have to instructions on creating an android development environment elsewhere)

a mini USB cable

a brain

general android knowledge can be helpful

Forgive this roughness of this instructable, I hadn't planned on making one, however a month after release nobody else has made one yet, I will make one just until someone makes a better one.

P.S. Adding games to the Atari flashback 8 gold is similar after a minor hadware mod. hint: The games are stored in an obb.

Step 1: Open Your Flashback and Connect It to a PC.

To open the unit you must remove the 7 screws, 4 are under the 4 feet pads, one is under the label, see image.

after the screws are removed take off the cover gently as not to break the wires connecting to the top.

Now plug in the Mini USB came on the mini USB plug on the unit circuit board, and then into your computer.

Wait a moment and the rk3036 will show up in your devices. When it does you are ready to go.

Step 2: Prepare Your Flashback

Now navigate to where you have ADB installed and run the following commands to prepare your unit to add games. (all commands are case sensitive)

"adb devices"

This command starts the adb daemon and verify the flashback is connected

"adb pull /system/atgames/all-games.ini"

This command copies the all-games.ini file you will need to modify to your computer.

"adb shell mount -o rw,remount,rw /system "

This command is where the risk starts, it tells your flashback to allow modifications to the system folder.

"adb shell mv /system/atgames/all-games.ini /system/atgames/all-games.bak"

This command creates a backup of the original all-games.ini to restore if needed later.

" adb shell ln -s /sdcard/Games/all-games.ini /system/atgames/all-games.ini"

This command creates a symlink from the original all-games.ini and points it to the NAND Flash for easy access.

" adb shell mount -o ro,remount,ro /system"

This command restores the original read only state to the system files.

Open NAND FLASH folder on the rk3036 device and create the folder "Games" (case is important here as well)

copy the all-games.ini file from your adb folder to the newly created "Games" folder

Try the system, make sure it still works correctly.
If it does not make sure the all-games.ini file is where it belongs and that there were no typos in the above or things will not work.

Step 3: Adding the Games

Note: games MUST be in .bin format (not just .bin extension) If they are in .smd or .mgd format they will not boot. Try to find a converter. (.sms and .gg also work but for the scope of this guide we will stick with genesis games)

The game can be named whatever you want but must have a bin extension and no spaces.

Ex.: Whatever.bin

drag the game to the created "Games" folder on the rk3036 device.

Now add a cover for the game with the same name and .png added.
format is PNG, resolution is 640x320.

Ex: Whatever.bin.png

Finally open the all-games.ini and add the following for each game, Replace the in bold with your own info.

[Game Name]



Description=this is a description of the game the real unit also included gameplay controls.

D=Pad-Does stuff

A=Other stuff


Now safe the all-games.ini and copy it to the "Games" folder you created

finally reboot the system and enjoy your new games.

Step 4: Restore to Stock (Optional)

If you feel the need to restore to stock follow these directions:

Navigate to your adb folder

run the following commands:

"adb devices"
This command starts the adb daemon and verify the flashback is connected

"adb shell mount -o rw,remount,rw /system "

This command is where the risk starts, it tells your flashback to allow modifications to the system folder.

"adb shell rm /system/atgames/all-games.ini"

This command removes the symlink you created.

"adb shell mv /system/atgames/all-games.bak /system/atgames/all-games.ini"

This command copies the original all-games.ini back into place.

" adb shell mount -o ro,remount,ro /system"

This command restores the original read only state to the system files.

Now navigate to the rk3036 device and delete the "Games" folder you created"

You have restored stock.

Step 5: Reassemble


1. Remove USB Cable

2. Replace cover

3. Flip upside-down and screw in 7 screws

4. Replace label and feet

5. Enjoy

Questions & Answers


Is there a way to backup and restore the Sega Genesis Flashback HD and the Atari Flashback 8 Gold? Also, does anyone have a backup image for the Atari Flashback 8 Gold? I am adding games to my Sega Flashback, but I blew up my Atari Flashback. It is stuck in a loop on the menu now, and the 01dd806188a53f0c5b7ab692b36c286c subfolder under /mnt/obb has disappeared.

My Sega Batch Code is D10608, Model is FB3680.

Mt Atari Batch Code is D10608, Model is AR3620.

Thanks. This has worked for me. However I have just a couple of questions.

1. To Add more games after completing this, do you just need to copy the games to the Games folder on the board and modify the .ini file?

2. It says that it can support .sms games, so how to I go about adding an .sms rom. Do add the games with the .sms extension and add to ini file but using the naming convention File=/sdcard/Games/whatever.sms and for the picture .sms.png?

Thanks again.

Possibly the batch code or model number on the bottom, but i dont know, the sticker seems completely printed, not a stamped number like you usually get.

My Batch Code is D10608, Model is FB3680

Hello. I have the same batch and model number as yours but when i enter the second command it says..... adb: error: remote object "adb pull /system/atgames/all-games.ini" does not exist ......any ideas why this is happening. Is there another directory i should try?

if you run this command:

adb shell am start -a android.intent.action.VIEW -n

you'll get a test screen with the build date, my date is in September 2017, if it is earlier you may have the OBB version and therefore this tutorial won't work properly. If you're familiar with OBB files you can repack it with a new all-games.ini but it's more risky and you should probably wait for a workaround if you're not sure of what you're doing.

Do you the command path if I want to pull the games directory on
Non obb sega flashback.?

Thank you i got it figured out now its a pain in the a$$ with the obb version but i was able to add more games.


someone has the all-game.ini file.have my unfortunately solved
