Getting Started with BigPEmu

Back to the Top

BigPEmu is a fairly straight-forward emulator to set up. Place your Atari Jaguar ROMs in Emulation/roms/atarijaguar or Atari Jaguar CD ROMs in Emulation/roms/xbox360/roms/atarijaguarcd. No additional setup is required. Read the Configuration section to learn more about BigPEmu and its folder locations.

To launch your ROMs in game mode, use Steam ROM Manager and use one of the following parsers to play your Xbox 360 ROMs:

  • EmulationStation-DE
  • Atari Jaguar/Jaguar CD - BigPEmu Proton

BigPEmu Folder Locations

Back to the Top

These file locations apply regardless of where you chose to install EmuDeck (to your internal SSD, to your SD Card, or elsewhere). Some emulator configuration files will be located on the internal SSD as listed below.

$HOME refers to your home folder. If you are on a Steam Deck, this folder will be named /home/deck (you will likely not see deck in the file path when navigating using the file manager).

Paths beginning with Emulation/.. correspond to your EmuDeck install location. If you installed on an SD Card, your path may be /run/media/mmcblk0p1/Emulation/roms/... If you installed on your internal SSD, your path may be /home/deck/Emulation/roms/..
