3d pen
did not have the budget to buy a 3d printer so got away with this cheap 3d pen to make some enclosure and attachments to the model.

Code

installing waveshare display overlays

Python
few commands in the terminal to install waveshare display overlays
Type the following commands:
i used putty to copy and paste these lines of code
git clone  https://github.com/swkim01/waveshare-dtoverlays.git
sudo cp waveshare-dtoverlays/waveshare32b.dtbo /boot/overlays/

making a few changes to boot config file

Python
Now to edit the boot config file:
after typing sudo nano /boot/config.txt
delete everything in that file and paste the driven code
After pasting save the file by pressing CTRL+X, then Y, then Enter.
Thenreboot the raspberry pi by typing the command:
sudo reboot

retrogame button config

Python
after installing retrogame using
cd
curl https://raw.githubusercontent.com/adafruit/Raspberry-Pi-Installer-Scripts/master/retrogame.sh >retrogame.sh
sudo bash retrogame.sh

When run, you’ll be asked to pick one of several control configurations.
pick 3 and press “y”

you will be asked for reboot press y

then open up terminal again
and type
sudo nano /boot/retrogame.cfg

now delete everything in the file

paste the following code and press ctrl+x then y to save.
# Sample configuration file for retrogame.
# Really minimal syntax, typically two elements per line w/space delimiter:
# 1) a key name (from keyTable.h; shortened from /usr/include/linux/input.h).
# 2) a GPIO pin number; when grounded, will simulate corresponding keypress.
# Uses Broadcom pin numbers for GPIO.
# If first element is GND, the corresponding pin (or pins, multiple can be
# given) is a LOW-level output; an extra ground pin for connecting buttons.
# A '#' character indicates a comment to end-of-line.
# File can be edited "live," no need to restart retrogame!

# Here's a pin configuration for the PiGRRL 2 project:

LEFT       6  # Joypad left
RIGHT     13  # Joypad right
UP        26  # Joypad up
DOWN      19  # Joypad down
LEFTCTRL  21  # 'A' button
LEFTALT   20  # 'B' button
SPACE     23  # 'Select' button
ENTER     24  # 'Start' button
ESC       18  # Exit ROM; PiTFT Button 1
Z          1  # 'X' button
X          0  # 'Y' button

# For configurations with few buttons (e.g. Cupcade), a key can be followed
# by multiple pin numbers.  When those pins are all held for a few seconds,
# this will generate the corresponding keypress (e.g. ESC to exit ROM).
# Only ONE such combo is supported within the file though; later entries
# will override earlier.
