Requirements
- A Raspberry Pi & MicroSD Card
- Download and Install RetroPie – Download RetroPie Here
- A keyboard and mouse – If you plan on using your Raspberry Pi to download BIOS files and ROMs
- Have at least one Genesis game ROM ready to test – The lr-genesis-plus-gx core accepts the following file extensions – .7z .bin .gen .md .sg .smd and .zip
- To play games on RetroPie you will of course need a controller – The 8bitdo M30 is one of the best RetroPie controllers and an excellent all-arounder for emulation and can also be connected by USB for even better performance in terms of latency.
Step 1 – Boot Your Raspberry Pi
The Sega Genesis emulator ‘lr-genesis-plus-gx’ typically comes preinstalled as part of the prebuilt RetroPie setup, so you should not have to install it manually.
Should you find that the lr-genesis-plus-gx emulator is not installed, then follow these steps:
- Go to the RetroPie options menu and select ‘RetroPie Setup’
- ‘Manage packages
- ‘Manage main packages’
- Scroll down and select lr-genesis-plus-gx’
- Finally, select ‘Install from pre-compiled’ binary’
- RetroPie will then download and install the Sega Genesis emulator
- Navigate back through the menu and then select ‘Exit’
Step 2 – Copy Your Genesis ROMs To ‘roms’ Folder
You will need to copy at least one of your Genesis game ROMs to the RetroPie ‘roms’ folder.
RetroPie with lr-genesis-plus-gx will be able to boot games stored in .zip files as well, so you can either place the game files directly into this folder, or within a .zip file.
Using Your Raspberry Pi To Move ROM Files
To get desktop mode up and running on your Raspberry Pi RetroPie setup, we will need to have the ‘Pixel’ desktop environment installed. Don’t worry, it’s really simple to do!
Upon booting your Raspberry Pi, scroll over to the RetroPie options menu and choose ‘RetroPie Setup’.
- RetroPie Setup (Access this from the RetroPie options menu)
- Configuration / Tools
- Raspbian Tools
- Install Pixel desktop environment
After installing the Pixel desktop environment, restart your Raspberry Pi. In RetroPie, simply navigate to ‘Ports’ and pick ‘Desktop’.
This will then launch into desktop mode, allowing you to explore your Raspberry Pi’s folders and files.
Next, you will need to transfer your Sega Genesis ROMs to the below location:
/home/pi/RetroPie/roms/genesis
Remotely Accessing Your Pi From A Windows PC
For those using a Windows PC, transferring files to your Raspberry Pi is very straight forward.
First, verify that your Raspberry Pi and PC are connected to the same network. Next, open Windows file explorer and enter ‘\\retropie’ in the address bar.
Give your Pi a minute to become visible on the network, as it might require some time to appear.
This will then connect to your Raspberry Pi and you will be able to see the ‘roms‘ folder.
Next, copy your game files from your PC to the /roms/genesis/ folder on your Raspberry Pi.
Once you have copied your games across to the roms folder, restart your Raspberry Pi or EmulationStation so the games can be indexed and visible for you to select.
Step 3 – Select A Genesis Game & Play
Once EmulationStation has restarted, navigate to the Genesis or Mega Drive section, which will display the number of available games, next, select the Genesis or Mega Drive menu and choose a game to enjoy!
This RetroPie Sega Genesis/Mega Drive page provides details on the state of Sega Genesis emulation on the Raspberry Pi as well as further configuration details for RetroPie Sega Genesis emulators.
