Extracting ROMs from Sega Mega Drive & Genesis Classics bought on Steam on Linux Mint 18.3

This post is also available in: frFrançais

Hey everyone. Klebs here and today, I’ll show you how you can legally purchase ROMs for the Sega Genesis/Mega Drive via Steam and rename them in a reader-friendly format. That way, you can use them elsewhere (e.g. emulators, Mega Everdrive, project MiSTer, etc.).

Before we begin

First, I’d like to thank ETA Prime for inspiring me to write this tutorial. In his video, he explains how to extract ROMs, rename them and use them in Retroarch, a multi-platform tool for emulators. To find out more:

Why then do I bother writing this if ETA Prime has already covered the subject? Two reasons:

  • he used Windows to explain the process
  • he showed how to rename the files without getting into too much details

If you also use Windows or can get around Sega’s odd ROM-naming conventions, ETA Prime’s video is all you need. However, if you prefer a Linux-oriented tutorial or a script that will rename the files for you, I’ll encourage you to keep reading.

Buying the games and locating them

You can legally buy certain Genesis/Mega Drive games on Steam individually or as part of a special package called Sega Mega Drive & Genesis Classics through this affiliate link on Humble Bundle. From this point on, I’ll use the term Sega Classics when I refer to Sega Mega Drive & Genesis Classics for the sake of simplicity.

Since the Sega Classics game isn’t natively available on Linux, we need to make sure Steam is configured to run all games in SteamPlay mode using Proton. That way, Sega Classics will appear in the list of purchased games making it available to be downloaded and installed.

Once installed, right-clicking on Sega Classics and choosing Properties will make the pop-up window appear (see image below).

Clicking on the Browse local files under the Local files tab will show the exact location of Sega Classics on the computer (see image below).

Normally, if the username is klebs and the default location set by Steam hasn’t been changed, the folder should be at /home/klebs/.steam/steam/steamapps/common/Sega\ Classics

In my case as the above screenshot clearly shows, the folder is located at /mnt/DATA/Jeux/Steam/steamapps/common/Sega\ Classics

Renaming the files

Assuming the username is klebs and is using Steam’s default game location, the following commands in the terminal will create a copy of the ROMs in another folder and create a CSV file with nano:

cd /home/klebs/.steam/steam/steamapps/common/Sega\ Classics
cp -R uncompressed\ ROMs/ ~/Documents/SegaROMS
cd ~/Documents/SegaROMS
nano segaclassicslist.csv

Before copying the list below in nano, it’s important to make sure nothing’s missing. Also, the original filenames should match those in the SegaROMS folder.

After saving and closing the CSV file, next up, it’s time to write a script that will rename the files:

nano segaclassicsrename.sh

#!/bin/bash
IFS=","
while read f1 f2
do
echo "rename from : $f1"
echo "to : $f2"
mv $f1 "$f2"
echo "done"
done < segaclassicslist.csv

After saving and closing the script, all that remains is to make it executable and run it:

chmod +x ./segaclassicsrename.sh
./segaclassicsrename.sh

If everything goes according to plan, the new filenames should be more straightforward.
