Download VPX installer from vpforums.org

Pick the latest one which is VPX6setup.zip at the time of this writing

Run this installer and be sure to install it in your EXISTING VPinMAME folder

From your VPinMAME directory, run “setup.exe”

Choose “Install”

From your VPinMAME directory, edit the file “DmdDevice.ini”

In the [pixelcade] section, add the COM port of your Pixelcade board. You must add the specific COM port here or the board will not be found.

Disable other pinDMD boards except pixelcade

If you are using a P2.5 sizes PinDMD (most popular size), then use:

matrix = rbg

If using a P3 – P6 sized PinDMD, then use:

matrix = rgb

From a command line from your VPinMAME directory, enter this command to test connectivity. Replace COM6 with the COM port of your Pixelcade board.

dmdext test -p COM6 -d pixelcade

Add some roms, placing them in the roms folder (look for patched roms if using color)

https://www.vpforums.org is a good place to find tables

From your VPinMAME directory, run “setup.exe”

Choose “Setup Defaults…”

Check “Use external DMD (dll)”

Click “OK”

Now click “Test”

Select a rom

Select “Game Options”

Ensure “Use external DMD (dll)” is checked

Click “OK”

Click “Start”

The Pixelcade PinDMD should now be displaying the game

If not displaying correctly, check the log file “DMDDevice.log”

If you like, you can also tweak the color.

Do this from “Default Options” so you don’t need to do for each game individually.

Now add some tables

https://www.vpforums.org is a good place to find tables

Tables should be copied to tables folder of your Visual Pinball installation.

Now if you want to add color, then follow these steps:

• Create a vpinmame\altcolor\ directory and copy the pin2dmd.pal file there. Note the Pixelcade PinDMD installer created this directory for you and added in some files.
• Copy the patched rom file to the vpinmame\roms directory 
• Enable ‘Colorize DMD (4 colors)’ in the rom setup of vpinmame for each colorized ROM you will be using
• Enable ‘Use external DMD (dll)’ in the rom setup of vpinmame for each colorized ROM you will be using.
• You’ll use the same table files and do not need to change those for color.

Lastly if you like, you can add a front end. Note that the Pixelcade listener (pixelweb.exe) cannot run at the same time as the Pixelcade PinDMD. So you’ll need to stop the Pixelcade listener (pixelweb.exe) before running a pinball table.

If you have pixelweb.exe running, then this REST API call will close it

http://localhost:8080/quit

A curl command is one way to make this call. curl is included in your Pixelcade installation

d:\arcade\pixelcade\curl.exe -s http://localhost:8080/quit

Here is a HyperSpin example. In this example, pixelweb.exe runs normally during HyperSpin until a Visual Pinball table has been launched. When a table is launched, this modification to the Visual Pinball.ahk script will stop pixelweb.exe when a Visual Pinball tables has been launched. At that point, Pixelcade PinDMD takes over and changes interactively with the pinball game. And then when you exit the table, pixelweb.exe is again launched.

For HyperSpin, Visual Pinball.ahk is located in RocketLauncher\Modules\Visual Pinball\Visual Pinball.ahk

Command to stop pixelweb.exe. Be sure and update for your correct path.

Run, "d:\arcade\Pixelcade\curl.exe" "http://localhost:8080/quit" , d:\arcade\Pixelcade\, Hide

Command to start pixelweb.exe

Run, d:\arcade\Pixelcade\pixelweb.exe, d:\arcade\Pixelcade\, Hide
