genesis and masterdrive folders...

DavidDraper

Specs:

RetroPie 4.7 (updated over 4.7 image downloaded for retropie.org)
Raspberry Pi 4B, 4GB ram
Raspian Buster
4 amp power supply from Vilros
8BitDO SN30, generic USB N64 controller, Vilros USB genesis controller.

about a week ago, I created a platforms.cfg file changing the masterdrive logo to genesis

megadrive_theme="genesis"
megadrive_platform="genesis"

today I have a genesis directory and a megadrive directory in my ROMS folder, and a megadrive directory (with files) in the downloaded_images and gamelist directory in the ~\retropi\configs\all\emulationstation\ directory.

I would like to get rid of either the megadrive ROM or genesis ROM directory to fee up space. But it seems that when I get rid of the megadrive ROM directory, the list of games and scraped artwork shows up in the genesis listing in emulation station, but when I select a game, but when I select a game, it does not open (I get the runcommand screen and then it quits back to the genesis list.)

When I delete the contents of the Genesis rom directory, the list of games in the genesis listing in emulation station does not appear on the main menu.

I would love to free up some space on my image by having only one copy of my genesis/megadrive roms. Any suggestions on how to set up my system so I can do this? Thanks.

I believe the genesis folder is symlinked to the megadrive folder normally. Since it is symlinked, you are only seeing what looks like two copies. It shouldn't actually have two full copies of all the files. However, if you would like to eliminate one, I think this would be the way.

The main problem is likely the es_systems.cfg file would need to be updated.

Look for it in either /etc/emulationstation (the default location) or in /opt/retropie/configs/all/emulationstation (the custom file location).

You should copy it from the default location and save it to the custom location so it won't get overridden during updates to the system.

Look for
<system>
<name>megadrive</name>
and change the following line:
<path>/home/pi/RetroPie/roms/megadrive</path>
to
<path>/home/pi/RetroPie/roms/genesis</path>
and you should be able to get rid of the megadrive folder.

Hopefully one of the gurus will jump in and correct me if I got the details wrong.

@yfzdude thanks! I will try it out.

As @YFZdude mentioned, the genesis folder is a symlink (shortcut) to the megadrive folder, so there's no need to remove it - it's not actually taking any space. You can leave it as is, it's ok - the scriptmodules expect a megadrive ROM folder and updating the MD emulators will re-create the folder.
