Video: GRS Build-A-Cade: The Ultimate Mini MultiCade
Build-A-Cade

A good friend and popular content creator of the retro gaming community, Glen Planamento (YouTube channel Glen’s Retro Show) and his partner Arcade Workshop have created an amazing new product called Build-A-Cade!

Build-A-Cade is a 1:6th mini MultiCade! That is, it allows adding your own classic arcade games to the machine. This is a project that you’ll assemble yourself and includes everything you’ll need to build it, with the exception of a Raspberry Pi (see here for supported options), USB-C power supply and a philips head screwdriver.

Multiple Control Panel Options

Glen sent one of the early units for review and guide development. The product is Amazing! I absolutely love this device, not just saying it because he’s a friend. It’s the type of quality product you’ve come to expect from GRS. I honestly don’t see how he can sell it for this price and make a profit (pre-order price is $89.99). Not only is the price exceptional, but the build quality is just as impressive. It feels very solid, well-designed and with the ability to swap control panels – you can build it the way you want.

The included manual will step you through the assembly process. The information below will be helpful if you’re new to the Build-A-Cade and RetroPie. The video above will step you through the entire process from unboxing, assembly, OS setup, copying your games, Game Play and much more. This guide will continue to be updated as new information and modding options are available for the Build-A-Cade. I hope you find it helpful, please comment in the above video if there is anything specific you’d like to see added here.

Modding Options

This is why we love this hobby, modding! Below are some options that are currently or will soon be available for the Build-A-Cade. As new options are identified, they will be added below.


Show Me

If you’re interested in seeing certain aspects of the Build-A-Cade, the following will launch a video to demonstrate what you’re looking for at the associated time-stamp. This makes it quick and easy to “see” exactly what you’re wanting without having to watch an entire video :


Supported Pi’s

Locating a Raspberry Pi, lately, has been quite difficult. Fortunately, you can use a Pi you may already own or any one of the following:

  • Raspberry Pi 3B
  • Raspberry Pi 3B Plus
  • Raspberry Pi 3A Plus
  • Raspberry Pi 4 Model B

If you don’t already have a Pi for the Build-A-Cade, check out RPiLocator. This tool searches all the sites that have Pi’s and can alert you when one is found.


Adding Games

There are a number of ways you can add your own games to the Build-A-Cade. Below are a few methods that may be helpful.


USB Stick

You can easily copy your games to the GRS Build-A-Cade using only a USB stick. I recommend using a USB stick that has an activity LED so you know once the copy has completed. Below are some instructions to help with that.

  • Insert your USB stick into your computer and format it as a FAT32 stick. If you’re not sure how, please see this.
  • Create a subfolder off the root of the USB stick called retropie.
  • Boot up the Build-A-Cade running RetroPie.
  • Insert the USB stick into one of the USB ports on the back of the Build-A-Cade.
  • The LED on the USB stick should blink for a bit, then stop and can be removed once the LED goes off. If your USB stick doesn’t have an LED indicator, leave it plugged in for at least two minutes.
  • Remove the USB stick from the back of the Build-A-Cade and insert it back into your computer. You should now see several folders under the /retropie subfolder that RetroPie created for you.
  • Copy your games into the /retropie/roms/arcade subfolder. Keep in mind, those that are vertical games will look best on the BaC.
  • After copying your games, insert the USB stick back into the BaC. Wait for the LED to stop blinking or leave it in the machine for at least 10 minutes to make sure the games copied.
  • Remove the USB stick.
  • Restart Emulation station (Press P1 button at the main menu), your games should now appear in the list. That’s it!

Network Copy

Another method of copying games to your Build-A-Cade is using the Network copy method. The following will assist you with how to do it:

  • Connect a keyboard to the Build-A-Cade and power it on.
  • Select Options.
  • Scroll to the bottom until you see WiFi and select it.
  • You’ll be prompted to set your WiFi Country. Select Yes and press Enter on the keyboard.
  • Move down until you see Localization Options and press Enter.
  • Select the WLAN Country option.
  • Select your country (you can press page up/down to move faster through the list). Then, press Enter and Enter again on the dialog.
  • Press the Tab key and select Finish and press Enter, then Yes to reboot now.
  • From your PC, open File Explorer and at the top bar enter \\retropie or \\[ip address of the Build-A-Cade] and press Enter.
  • Navigate into the roms share, then the arcade sub folder. You should see the included/licensed game, robby.zip.
  • Copy your own arcade game roms into this subfolder by dragging and dropping them into the arcade sub folder. *NOTE: some classic arcade games may need samples to play correctly, copy any samples to the \bios\mame2003\samples sub folder.
  • Once all games have been copied, on the Build-A-Cade press the P1 button from the main menu, select Quit Restart Emulation Station.
  • Once Restarted, you can now play the games on your Build-A-Cade!

Operation

The following are some helpful operational tips while using the included 3-button 1-joystick control panel, all of which have been mapped automatically for you :

Below are some game ideas for the control panels. This list is a work-in-progress 🙂

3 Button 1 Stick (Included with the Build-A-Cade)

For the control panel that is included with the Build-A-Cade, it has one action button and a P1, P2 and a single joystick. For this panel, I recommend the following games to start off with.

Troubleshooting

The following are some troubleshooting points that you may find helpful:

  • I completed the assembly, but don’t see anything on the display. Why? Try removing the microSD card from the extender and inserting it directly into the Pi, then power-on the BaC. If the display comes on, power off the BaC and re-insert the microSD extender cable and make sure it’s fully seated. Then re-install the microSD into the extender and power on the BaC. If everything works, you’ve fixed the issue. If this didn’t fix the issue, it could be a defective display or bad microSD extension cable. Contact support here.
