Retropie

Content

Retropie is a Raspberri Pi OS distribution with a bunch of emulators and drivers embeded. An other distribution to have a look at is Mega Retro.

Roms

Visit these websites to download some roms but never forget that it will be illegal to download a game without paying it at first. That said, I only downloaded games previoulsy bought when I was a kid. Basically those I still have the cartbridge or the CD of.

Roms can use a lot of your storage. It is common to see a PSX game somewhere between 300Mo and 600Mo. It can be a good idea to keep them on an SSD drive mounted via USB.

Raspberry Pi OS mounts USD external storages in /media. Mine got mounted by default in /media/usb0. Retropie on the other hands requires you to place roms in /home/pi/Retropie/roms/<platform>.

From that point there are 2 options:

  • Create a symbolic link from /media/usb0/<platform> to /home/pi/Retropie/roms/<platform>: ln -s /media/usb0/<platform> /home/pi/Retropie/roms/<platform>
  • Mount the USB storage in /home/pi/Retropie/roms

Memory Card

Every emulator has its own method. Most of our games are Playstation 1 games so Memory Card saves are located in /home/pi/RetroPie/roms/psx/.

Game controllers

The chosen controllers are 8BitDo SN30 Pro+.

Eventually, the file /opt/retropie/configs/all/retroarch-core-options.cfg needs to be edited. At least to activate the joypads.

Important lines are pcsx_rearmed_pad1type = "dualshock" and pcsx_rearmed_pad2type = "dualshock".
