Retrogame has been a hit for the Raspberry Pi computer. There are many ready images (games) that you can download and play with the Raspberry Pi main board. Now with Compute Module 4, you can get as many variations as you want. There are 32 variations of Raspberry Pi Compute Module 4. It is compact and slim, and super powerful.

The GPi Case 2 is compatible with all Raspberry Pi CM4 variants (wireless and non-wireless). However, we recommend CM4 with Wireless and Lite versions. The reasons are:

  • There is NO Ethernet on GPi Case 2, so the only remote access method into the RetroPie, RecalBox or other OS is via wireless SSH. If you use non-wireless CM4, it will be very troublesome work. Therefore, please get the CM4 with built-in wireless
  • CM4 with built-in eMMC CAN NOT expand memory storage via microSD card. If you get a CM4 with eMMC, you will need to stick with the eMMC size for the OS and ROM (games). Even though GPi Case 2 has a microSD card slot, that is meant for CM4 Lite. Therefore, please get the CM4 Lite version where you can choose the microSD card size. If you have only CM4 with eMMC, please choose a larger eMMC capacity, and do understand that it CAN NOT be expanded.

 

 


 

The Perfect Hand-held Retrogame Console for Compute Module 4

Specially designed and made for all variants of CM4, wireless or non-wireless, with eMMC or no eMMC (Lite), and RAM size of 8GB down to 1GB. You can build your favorite hand-held retro game console with it. The GPi Case 2 comes with a 3-inch, 640x480 IPS LCD Screen which is more than sufficient for most 8-bit retro games. It is also portable with a 4000mAh Li-io rechargeable battery included in the case. With the huge battery capacity, you can play your favorite game for at least several hours! It can be charged via the USB-C port at the bottom of the case or the USB-C port on the docker.

The Design

As an homage to the 8-bit handheld game console, Game Boy, not only does it carry the same looks, but it also includes additional features like X/Y buttons hidden L/R shoulder buttons, and POWER.

Besides the USB-C port for charging the battery, the GPi Case 2 also comes with a 3.5mm headphone jack, at the bottom of the case. For gamers, the case comes with an extra Turbo button, Hotkey, and save energy function with a save energy button.

Technical Specifications

 

The Deluxe Edition

 

GPi Case 2 Dock

This is the Deluxe Edition that comes with a Special Dock. The dock comes with:

  1. USB 2.0 Port
  2. USB 2.0 Port
  3. USB-C Power Input port
  4. HDMI Output port

All the ports are located at the back of the Dock.

 

Besides the RetroPie or Recalbox image, you will install a patch. This is due to both Retropie and Recalbox default display/multimedia output being HDMI, while GPi Case 2 uses GPIO for the output display onto the 3.0-inch screen. Thus, the patch.  You can download the patch here.

To utilize the Safe Shutdown, a script is needed. You can get it from here: https://github.com/RetroFlag/GPiCase2-Script

 

Loading OS Image, Patch, and Script into microSD Card

  1. If you get a CM4 Lite, please follow this guide.
  2. If you are getting the MakerDisk microSD card, it comes with the Raspberry Pi OS preloaded in it. However, with the GPi Case 2, you will most likely want to install RetroPie or Recalbox OS.
  3. Insert the microSD card into a USB microSD card adapter.
  4. Insert the USB microSD adapter into your computer/laptop USB port.
  5. Insert the CM4 Lite into the GPi Case 2, make sure the orientation is correct and both the CM4 bottom connectors are fully inserted.
  6. Now you can use the Raspberry Pi Imager to flash RetroPie, Recalbox, or an alternative OS onto it. Select it under Operating System -> Emulation and game OS.
  7. Select the microSD card under Choose Storage.
  8. Before you "Write", you can also click the "advance settings", gear icon at the bottom-right corner to configure the WiFi SSID, password, and enabled SSH.
  9. Once the imager is done writing the OS into the microSD card, unplug the USB adapter and re-insert it into the USB port.
  10. Turn on the GPi Case 2, via the power switch, or power it up with the USB-C cable.
  11. Download the GPi Case 2 patch here. Unzipped it, and follow the instructions in the readme.txt file to install the patch.
    1. Copy CPi_Case2_patch_XXX system folder to microSD card root drive. Choose the folder based on the OS you flash into the eMMC.
    2. Enter CPi_Case2_patch_XXX system folder and run install_patch.bat
    3. The patch is done. You can now eject the microSD card from your computer
  12. Install the microSD in the GPi Case 2.
  13. Power up the GPi Case 2, and wait for around 1 minute for the 1st boot. The OS should boot up and the 3.0-inch screen should show some info.
  14. You can then follow the instructions here to install the script.
  15. Good luck and enjoy playing games!

Loading OS Image, Patch and Script into CM4's eMMC

  1. If you get a CM4 with eMMC, please go along with the following guide.
  2. Insert the CM4 with eMMC into the GPi Case 2, make sure the orientation is correct and both the CM4 bottom connectors are fully inserted.
  3. Connect a USB micro B cable to the USB micro B jack at the back of the GPi Case 2's screen. It is the micro-B jack, NOT USB-C jack.
  4. Connect the other end of the USB cable to the laptop or computer USB port.
  5. Install rpiboot which lets the computer recognize the GPi Case 2 with CM4 eMMC installed as a storage device. Download it here: https://github.com/raspberrypi/usbboot/raw/master/win32/rpiboot_setup.exe.
  6. Run the rpiboot with admin privileges after the installation.
  7. Turn on the GPi Case 2, via the power switch, or power it up with the USB-C cable.
  8. The rpiboot should now recognize the eMMC on CM4 as USB storage. If it doesn't, make sure you really seat the CM4 into the GPi Case 2 carrier board. The two connections should generate a very affirmative snapping sound. You really have to jam it in there! Reseat the CM4 and try again.
  9. Once the eMMC shows up as a drive, just use Raspberry Pi Imager to flash RetroPie or an alternative OS onto it.
  10. Download the GPi Case 2 patch here. Unzipped it, and follow the instructions in the readme.txt file to install the patch.
    1. Copy CPi_Case2_patch_XXX system folder to CM4's eMMC root drive. Choose the folder based on the OS you flash into the eMMC.
    2. Enter CPi_Case2_patch_XXX system folder and run install_patch.bat
    3. The patch is done. You can now eject the drive from your computer
  11. Remove the USB micro B cable from the GPi Case 2. If you do not remove the cable, it will not boot up.
  12. Power up the GPi Case 2, and wait for around 10 seconds, the OS should boot up and the 3.0-inch screen should show some info.
  13. You can then follow the instructions here to install the script.
  14. Good luck and enjoy playing games!
