-[[https://docs.libretro.com/|RetroArch]] (formerly SSNES), is a ubiquitous frontend that can run multiple "cores", which are essentially the emulators themselves. The most common cores use the [[https://www.libretro.com/|libretro]] API, so that's why cores run in RetroArch in Batocera are referred to as "libretro: (core name)". RetroArch aims to unify the feature set of all libretro cores and offer a universal, familiar interface independent of platform. +RetroArch has [[emulators:retroarch|its own page]].

-RetroArch offers a **Quick Menu** accessed by pressing ''[HOTKEY]'' + {{:wiki:south.png?nolink&20|South button (B SNES)}} which can be used to alter various things like [[:advanced_retroarch_settings|RetroArch and core options]], and [[:remapping_controls_per_emulator|controller mapping]].

-<WRAP center round info 60%> +Created by [[https://www.richwhitehouse.com/jaguar/|Rich Whitehouse]], BigPEmu is the first Atari Jaguar emulator to offer compatibility with the entire library of commercially sold cartridges. It's worth noting that it was originally a closed-source emulator that was integrated into the Atari50 compilation. It has support for Jaguar CD games.
-This emulator is only available for X86-64 versions of Batocera, due to the use of a wine layer for its execution. +

-=== Informations === +This emulator is only available for x86_64.
-Created by [[https://www.richwhitehouse.com/jaguar/|Rich Whitehouse]], BigPEmu is the first Atari Jaguar and Jaguar CD emulator to offer compatibility with the entire library of commercially sold cartridges, along with excellent performance and a wide variety of unique features. It's worth noting that it was originally a closed-source emulator that was integrated into the Atari50 compilation. Without a doubt, it is the best Jaguar emulator.+
  
-=== Jaguar CD === +=== Jaguar Game Drive ===
-The BigPEmu emulator also supports the Jaguar CD format (Bin/Cue). For now, you can copy your bin/cue files to the ''/userdata/roms/jaguar/''folder to display them in EmulationStation.+
  
-=== Jaguar Game Drive === +Some games are locked to be used on the Jaguar Game Drive (a hardware extension for the Jaguar console). BigPEmu has an option to emulate this hardware and allow these locked games to be played. This option can be enabled by pressing the ''[Esc]'' key, then going to **System** -> **Settings** -> **Force JGD Emulation**.
-BigPEmu has the great advantage of having perfect compatibility for homebrew games. However, it is worth noting that some games are locked to be used on the Jaguar Game Drive (a hardware extension for the Jaguar console). BigPEmu has an option to emulate this hardware and allow these locked games to be played. You can enable this option in the settings of BigPEmu by accessing it via the ESC key on your keyboard. +

-BigPEmu supports per-game profiles. This is accomplished by creating a BigPEmu configuration file of the same name as the software image you're loading, with a .bigpcfg extension. For example, if your software image file is named Cybermorph.j64, you would create a Cybermorph.bigpcfg file alongside it.+BigPEmu supports per-game profiles.

For example, if your software image file is named ''Cybermorph.j64'', you would create a ''Cybermorph.bigpcfg'' file alongside it.
  
-In order to create the per-game configuration file, it's recommended that you just make a copy of your central BigPEmu configuration file. Under Windows, you can find this file at ''/userdata/saves/bigpemu-bottle/drive_c/users/root/AppData/Roaming/BigPEmu/BigPEmuConfig.bigpcfg'' +In order to create the per-game configuration file, it's recommended that you make a copy of your central BigPEmu configuration file.
