How to use in the Raspberry/Ubuntu Mate/Kali/Retropie system

There are two ways to use it

The First Method

Directly download the image we created and burn it into the micro SD card and insert it into the RaspberryPi. (Q:How to burn?)
Image download see the image download section of the Download Resources

The second method

Step 1, install the latest official image of various systems (Q:How to install？)
(1)Download the latestRaspbian/Ubuntu Mate/Kali-linux/Retropieimage from the official
(2) Format the Micro SD card using SDFormatter
(3) Use Win32DiskImager to burn the official image to the Micro SD card
Step 2, connect with the Raspberry Pi





Align right-side to insert the LCD screen             
Plug-in MicroSD card, connect network and power   





Step 3, install the LCD driver (the Raspberry Pi needs to connect to the Internet)
(1) Log in to the Raspberry Pi terminal(SSH remote login user name and password, see the image download of the Download Resources) (Q:The ssh can't connect?)
(2) Execute the following command to get the LCD driver (after copying, click the right mouse button in the Putty window to paste):
sudo rm -rf LCD-show
git clone https://github.com/goodtft/LCD-show.git
(3) Modify the LCD driver by comparing it with the local driver（Raspbian system does not need to be modified,The local driver download see the driver download section of the Download Resources）
(4) Execute the following command to install the LCD driver (after copying, click the right mouse button in the Putty window to paste):
chmod -R 755 LCD-show
cd LCD-show/
sudo ./MHS32-show
(5) After the LCD driver is installed, the system will automatically restart. After the startup is successful, it will be displayed and touched normally.
Note:
A. the file name of the LCD driver may not be LCD-show, you need to execute the command according to the actual situation.
B. You can directly copy the local driver to the system for LCD driver installation,The local driver download see the driver download section of the Download Resources
C. Ubuntu system default SSH is not enabled, the specific method of opening seeRaspberryPi Ubuntu-mate open ssh instructions
D. Ubuntu-18.04 system ssh connection may fail, the specific solution is shown in RaspberryPi Ubuntu-mate-18.04 ssh connection failure solution description
E. The retropie-rpi1_zero system cannot log in via SSH (no network port and wifi module). You need to copy the driver through the serial port. For details, see RaspberryPi Zero open serial instructions
F. After installing this driver, the HDMI output will be disabled. To switch back to the HDMI display, execute:
sudo ./LCD-hdmi
G. Retropie system game installation and setup instructions see RaspberryPi Retropie using instructions
