Here are my modified instructions for a “20” monitor

The original instructions are made for a 19″ monitor, I had to slightly modify for a 20″ monitor which actually measures to be just over 19″ (19 3/4″) width.  Hope this helps!

Initial retropie software install to SD card:

You can either begin the retropie setup before your arcade is built or in parallel to the woodwork.  I had my pi setup before woodwork was done which made it easy to plug and play once the woodwork was completed.   In order to setup retropie, follow the following steps which walk through download, extracting, installing, and follow on tips for setting up wifi, additional emulators (software to run games for game systems such as Nintendo or Super Nintendo), configure controllers, and even transferring games (also known as ROMs).  So let’s get started by following the steps from the official retropie guide.

Note: You’ll need as SD card reader or way to transfer and “etch” to SD card.  Need an SD card and/or reader? Here’s some options:

SD CARD:

Gigastone 128GB Micro SD Card, Gaming Plus, Nintendo Switch Compatible, High Speed 100MB/s, 4K Video Recording, Micro SDXC UHS-I A1 Class 10

SD CARD READER:
Micro SD Card Reader, 3-in-1 USB 2.0 Memory Card Reader OTG Adapter for PC/Laptop/Smart Phones/Tablets

Methods to connect remotely to retropie/rasberry pi:

One of the best ways to configure the retropie after initial setup is to add the SSH option within retropie.  I recomend using Filezilla which is a free FTP client options that also support SSH (read this link for more info).  Chrome is an alternative now using the app  or there is another iphone app out called Shelly that allows connection to your pi.

When editing my config.txt, I tried both changing the retropie software for resolution as well as downloading the config.txt via SSH, modifying, and reuploading.  In the end it was not taking to retropie, so I had to go in with my iMac via the terminal (similar to command prompt) and used the “vi editor” within terminal to edit the file.

There is also a mobile app I use for continuous changes when taking the pi with me on vacation and plugging into HDMI, I added a comments for when I’m using HDMI vs DVI so I can easily comment out.  Here’s a copy of my config.txt file:   CONFIG.TXT
