---

Option 1: Virtual Machine (only for emulators)

Prerequisites

• Either VMware Player (free), VMware Workstation Pro (paid) or Oracle VirtualBox (free)
• Debian 11.1 ISO (newer versions not tested)
• VirtualHere USB Client for Windows, Linux or MacOS

Guide

1. Make a new virtual machine with Debian in your software of choice. Select your ISO file and choose the appropriate operating system (Linux -> Debian 11.x 64-bit) if you're asked. To make sure your VM is accessible on the network, please follow the instructions in the troubleshooting section on this page (either for VirtualBox or VMware).

2. When first booting the Debian VM, select Graphical install. In the configuration, leave everything on default. Only change your language, set debian as hostname, don't set a root password, choose an account name and password, set partition to "yes" and /dev/sda for the GRUB bootloader.

3. After rebooting, log in with your password. Then click the menu on the upper left corner, search for "Terminal" and open it.

4. Run the following commands (you can copy and paste with right click):

   sudo apt install usbip hwdata curl python build-essential -y
   echo "usbip-core" | sudo tee -a /etc/modules
   echo "usbip-vudc" | sudo tee -a /etc/modules
   echo "vhci-hcd" | sudo tee -a /etc/modules
   
   echo "dtoverlay=dwc2" | sudo tee -a /boot/config.txt
   echo "dwc2" | sudo tee -a /etc/modules
   echo "libcomposite" | sudo tee -a /etc/modules
   echo "usb_f_rndis" | sudo tee -a /etc/modules
   
   sudo apt install -y git
   git clone https://github.com/Berny23/LD-ToyPad-Emulator.git
   cd LD-ToyPad-Emulator
   
   printf '\necho "usbip-vudc.0" > UDC\nusbipd -D --device\nsleep 2;\nusbip attach -r debian -b usbip-vudc.0\nchmod a+rw /dev/hidg0' >> usb_setup_script.sh
   sudo curl https://raw.githubusercontent.com/virtualhere/script/main/install_server | sudo sh
   
   sudo cp usb_setup_script.sh /usr/local/bin/toypad_usb_setup.sh
   sudo chmod +x /usr/local/bin/toypad_usb_setup.sh
   (sudo crontab -l 2>/dev/null; echo "@reboot sudo /usr/local/bin/toypad_usb_setup.sh") | sudo crontab -

5. Reboot you device with this command:

   sudo shutdown -r now

6. Log in again and run the following commands in the terminal:

   curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh | bash
   export NVM_DIR="$HOME/.nvm"
   [ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"
   [ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"
   
   nvm install 11
   sudo setcap cap_net_bind_service=+ep `readlink -f \`which node\``
   npm install --global node-gyp@8.4.1
   npm config set node_gyp $(npm prefix -g)/lib/node_modules/node-gyp/bin/node-gyp.js
   
   cd LD-ToyPad-Emulator
   npm install

Usage

1. Start the virtual machine if it's not already running. Then start the VirtualHere USB Client and double click on LEGO READER V2.10.

2. Run the emulator server with this command if you are in the correct folder (otherwise run cd LD-ToyPad-Emulator first):

   node index.js

3. Type http://debian in a browser to use the emulator.

   If you want to turn it off, just press Ctrl + C in the terminal, then use the command sudo shutdown now to power off the virtual machine or just pause it from the host.

4. Finally, start your console emulator and the game itself (e.g. Cemu).

Option 2: Single Board Computer

Prerequisites

• Raspberry Pi Zero W ($10) or similar single board computer with Network support
  • NOTE: Will NOT work with Rapsberry Pi: 2, 3, 3A, 3A+, 3B, 3B+. These models lack the ability to become a usb gadget.
• USB A to micro USB A cable that supports data transmission (e. g. your phone's charging cable)
• 2 GB+ Micro SD card
• Internet connection on your PC and single board computer

Guide

1. If you're using a Raspberry Pi Zero W, flash Raspberry Pi OS Lite to your SD card using the Raspberry Pi Imager tool and follow this as well as this instruction for headless installation.

2. Connect your device to your PC via USB cable (don't use the port on the edge of the Pi Zero!).

3. Use SSH to run the following commands (Don't know the IP address? Try this IP scanner.):

   echo "dtoverlay=dwc2" | sudo tee -a /boot/config.txt
   echo "dwc2" | sudo tee -a /etc/modules
   echo "libcomposite" | sudo tee -a /etc/modules
   echo "usb_f_rndis" | sudo tee -a /etc/modules
   
   sudo apt install -y git
   git clone https://github.com/Berny23/LD-ToyPad-Emulator.git
   cd LD-ToyPad-Emulator
   
   printf '\necho "$UDC" > UDC\nsleep 2;\nchmod a+rw /dev/hidg0' >> usb_setup_script.sh
   
   sudo cp usb_setup_script.sh /usr/local/bin/toypad_usb_setup.sh
   sudo chmod +x /usr/local/bin/toypad_usb_setup.sh
   (sudo crontab -l 2>/dev/null; echo "@reboot sudo /usr/local/bin/toypad_usb_setup.sh") | sudo crontab -

4. Reboot you device with this command:

   sudo shutdown -r now

5. Connect via SSH again and run the following commands:

   curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh | bash
   export NVM_DIR="$HOME/.nvm"
   [ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"
   [ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"
   
   nvm install 11
   sudo setcap cap_net_bind_service=+ep `readlink -f \`which node\``
   npm install --global node-gyp@8.4.1
   npm config set node_gyp $(npm prefix -g)/lib/node_modules/node-gyp/bin/node-gyp.js
   
   cd LD-ToyPad-Emulator
   npm install

Usage

1. Run the emulator server with this command if you are in the correct folder (otherwise run cd LD-ToyPad-Emulator first):

   node index.js

2. Type your single board computer's IP address in a browser to use the emulator.

   If you want to turn it off, just press Ctrl + C in the cmd window, then use the command sudo shutdown now to safely power off the device.

Update

To update this software, just pull the latest changes by running the following 3 commands:

cd LD-ToyPad-Emulator
rm package-lock.json
git pull
npm install

Only use the following command if you get an error, then run the last two lines from above again:

git reset --hard

Troubleshooting

RPCS3 cannot detect the Toy Pad

This solution works only for RPCS3 and will break the Toy Pad detection with every other emulator!

Download and run Zadig.

Click on Options and tick List All Devices. Select LEGO READER V2.10 in the dropdown menu, then select WinUSB if it's not already selected, click on the Replace Driver button and on Yes in the dialog.

After the installation has finished, exit Zadig and restart RPCS3. If you get stuck on the main menu, just close the game, right-click on it in the RPCS3 games list, select Change Custom Configuration, switch to the Network tab and choose Disconnected in both drop-down menus. The game will now correctly detect the Toy Pad.

To undo the changes from Zadig, you have to rollback the driver:

1. Open Device Manager, scroll down to USB devices and expand the section.
2. Double-click LEGO READER V2.10.
3. Switch to the Driver tab, click Previous Driver, select the first option and click yes.

Webpage not reachable (Oracle VirtualBox)

Shutdown your virtual machine (icon in the upper right corner). In VirtualBox's manager, click your image and open Settings. Under Network change Attached to: to Bridged Adapter and click ok. Start your virtual machine.

Webpage not reachable (VMware)

Shutdown your virtual machine (icon in the upper right corner). Right-click on your virtual machine's name in VMware Workstation or VMware Player and click Settings.... Click on Network Adapter and select Bridged. Click OK and start your virtual machine.

Error: listen EADDRINUSE: address already in use :::80

Either close any other software that is using the port 80 or manually edit the last line of index.js (with nano index.js, edit the line, then press Ctrl + O, Enter and Ctrl + X).

If you did this, you may need to append your selected port to the address in the browser (like http://debian:500 or http://192.168.0.165:500 if your port is 500).

VirtualHere USB Client doesn't show LEGO READER V2.10

When installing the virtual machine, you have to set the hostname to debian.

Alternatively, copy the following command and replace YOUR_IP_ADDRESS with your virtual machine's IP address (it looks like 192.168.X.X, run hostname -I to show it). After you've done this, run the modified command while you're inside the LD-ToyPad-Emulator folder.

git reset --hard ; printf '\necho "usbip-vudc.0" > UDC\nusbipd -D --device\nsleep 2;\nusbip attach -r YOUR_IP_ADDRESS -b usbip-vudc.0\nchmod a+rw /dev/hidg0' >> usb_setup_script.sh ; sudo cp usb_setup_script.sh /usr/local/bin/toypad_usb_setup.sh

Webpage not reachable under http://debian/

If you're using a virtual machine, make sure you've applied the solution specific to your software first (VirtualBox or VMware)!

After that, run the command hostname -I in your virtual machine (or on your single board computer) and type the IP address that looks like 192.168.X.X in your webbrowser.
