Long summary of problem: The version of Retropie I'm using(see build summary below explanation) was pre-mapped and configured to use the Game Hat, but it has NOT mapped the two shoulder buttons. For most of the games I play, this is a non-issue, but when I load up SNES games this obviously comes to be an issue as the lack of L and R buttons. I bought a Waveshare Game Hat recently and decided to build it today. I followed the instructions carefully, and when I turned it on, the screen displayed 'No Signal.' I realized that I didn't have the GPIO pins lined up properly, so I turned it off, removed the battery, removed the SD card, unplugged the Pi (3B+), and plugged it back in making. This is not a review!!!my first impressions on waveshare game hat with raspberry pi 3 comparing against Retrogame console.Buy from here.https://www.aliexpres.

Hardware Connection

Insert Raspberry Pi to Game HAT (GPIO pins header)
Connect HDMI. Insert the HDMI connector to screen and Raspberry Pi
If you use Raspberry Pi Zero/Raspberry Pi Zero W, you need to use HDMI cable
Toggle the Battery switch of Game HAT to OFF, and mount 18650 battery to it.

Method 1, Use Pre-build Image

Unzip the ZIP and write the image file to TF card
Inset the ready TF card to your Raspberry Pi, toggle Battery switch to ON.
If the battery is low, Raspberry Pi cannot startup. In this case, you can connect a 5V/2A power supply to the Power interface of Game HAT for charging. The charge indicator will flicker when charging. You can play during charging but note that Raspberry Pi will reboot automatically if you disconnect the power supply.
If the battery is full Raspberry Pi will start up normally.
After entering OS, you can choose emulators by joystick. For example, choose the Nintendo emulator and press “A” to confirm.
You can see there are some games. Choose one and press “A” to enter. After the cutscene, you can press the “A” or “Start” key to start the game.
If you want to exit from the current game, you can press buttons “Start” and ”Select” at the same times
You can press the 4 buttons on the right side of Game HAT to adjust volume and brightness of LCD, Press Menu to open the OSD menu, and press Up/Left or Down/Right to choose options, then press Menu to confirm option and adjust it. Finally, press Exit to exit the OSD menu.

Method 2. Install Driver Manually (Retropie)

The driver cannot support Retropie-v4.7, please wait for updating

Please download the Retropie image on the Retropie website according to the type of your Raspberry Pi.

Download and unzip it to get .img file
Write the .img file to TF card by Win32DiskImager.exe
After writing, copy the Game HAT driver you download to the root directory of the TF card.
Open the config.txt file which is also on the root directory, append these statements to the config file

Inset the TF card and a USB keyboard to Raspberry Pi, open Battery switch to power on Raspberry Pi. After booting, press F4 to open Terminal.
Execute commands as blow. (Make sure you have copy driver to Raspberry Pi)

Reboot Raspberry Pi. Long press the “A” button (other keys are OK as well) to enter the buttons configuration page. Configure keys as below. You can also long-press “A” or other buttons to pass the configuration.

After configuring:
Press the “A” button to save configurations and exit.
Or press the “B” button to cancel configurations and exit without saving.
The configuration is finished and you can try to play games now.

Add New Game

Maybe the default games in the test image are not those you want, you can also add games as you like.

Size of most games are always large, so we need to expand the filesystem fist. Choose RASPI-CONFIG on configure page and press enter

Choose 7 Advanced Options -> A1 Expand Filesystem, Enter->Finish, (physical keyboard is required)

Choose OK, and reboot.
Download ROMS of games you like

Connect your Raspberry Pi to the network (Make sure the network you connect is in the same LAN as your PC). Find SHOW IP in Retropie list, press “A” to query the current IP address of your Raspberry Pi.

Open it with the IP address on your PC

Then on the emulator choose the page, you can press “Start”->QUIT->RESTART EMULATIONSTAION, press “A” to confirm. Then restart the emulator, you can find the game added.

For more operations, you can read Retropie Instructions

Method 2. Install Driver Manually (Recalbox)

Waveshare Game Hat Driver

Download the newest Recalbox image

Write the image to your TF card and modify config.txt file

Add lines to config.txt file:

Access Recalbox by SSH (network is required)

User：root Passwird：recalboxroot

Modify recalbox file

Change the line 'controllers.gpio.enabled=0' to 'controllers.gpio.enabled=1' Catia v6 student version download.

Change the line 'controller.gpio.args=map=1,2' to 'controllers.gpio.args=map=4 gpio=5,6,13,19,21,4,26,12,23,20,16,18,-1' Apowersoft screen recorder no sound android.

Modify recalbox-config.sh file

After the following lines
mode='$2'
extra1='$3'
extra2='$4'
Add a line extra3='$5'
Find the following part
Change map='$extra2' to map='$extra2 $extra3'

Save and reboot Raspberry Pi. After booting, long-press any buttons of Game HAT to configure the keys.
