Videopac+ G7400
The Videopac+ G7400 is a console developed by Philips. It was released in 1983.
Place your ROMs in /userdata/roms/videopacplus. Most games were also backwards compatible with the original Videopac/Magnavox Oddyssey2, to play games in this backward compatibility mode adjust the ADVANCED SYSTEM SETTINGS → MODEL or simply place your ROMs in /userdata/roms/o2em.
This system scrapes metadata for the “videopacplus” group(s) and loads the videopacplus set from the currently selected theme, if available.

Emulators
RetroArch
RetroArch (formerly SSNES), is a ubiquitous frontend that can run multiple “cores”, which are essentially the emulators themselves. The most common cores use the 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 configuration
RetroArch offers a Quick Menu accessed by pressing [HOTKEY] + 
which can be used to alter various things like RetroArch and core options, and controller mapping. Most RetroArch related settings can be altered from Batocera's EmulationStation.
Standardized features available to all libretro cores: odyssey2.videomode, odyssey2.ratio, odyssey2.smooth, odyssey2.shaders, odyssey2.pixel_perfect, odyssey2.decoration, odyssey2.game_translation
ES setting name batocera.conf_key | Description ⇒ ES option key_value |
|---|---|
| Settings that apply to all cores of this emulator | |
GRAPHICS BACKEND odyssey2.gfxbackend | Choose your graphics rendering ⇒ OpenGL opengl, Vulkan vulkan. |
AUDIO LATENCY odyssey2.audio_latency | Audio latency in milliseconds, turn it up if you hear crackles ⇒ 256 256, 192 192, 128 128, 64 64, 32 32, 16 16, 8 8. |
THREADED VIDEO odyssey2.video_threaded | Improves performance at the cost of latency and more video stuttering. Use only if full speed cannot be obtained otherwise. ⇒ On true, Off false. |
libretro: O2EM
O2EM is an open-source Magnavox Odyssey² emulator. This is the libretro port of that.
libretro: O2EM configuration
ES setting name batocera.conf_key | Description ⇒ ES option key_value |
|---|---|
| Settings that apply to all systems this core supports | |
EMULATED HARDWARE global.o2em_bios | Choose what Odyssey/Videopac system to emulate ⇒ Odyssey 2 (NTSC) o2rom.bin, Videopac G7000 (European) c52.bin, Videopac+ G7400 (European) g7400.bin, Videopac+ G7400 (France) jopac.bin. |
CONSOLE REGION global.o2em_region | To force 60hz or 50hz if the auto detection fail ⇒ Autodetect autodetect, NTSC NTSC, PAL PAL. |
SWAP GAMEPADS global.o2em_swap_gamepads | Some games accept player 1 input from controller 2 ⇒ Off disabled, On enabled. |
CROP OVERSCAN global.o2em_crop_overscan | Remove the border around the edges of the screen ⇒ Off disabled, On enabled. |
GHOSTING EFFECT global.o2em_mix_frames | Simulate CRT phosphor ghosting effects ⇒ Off disabled, Simple mix, Ghosting (65%) ghost_65, Ghosting (75%) ghost_75, Ghosting (85%) ghost_85, Ghosting (95%) ghost_95. |
AUDIO FILTER global.o2em_low_pass_range | Soften the hash sound effect from some games ⇒ Off 0, 10% 10, 20% 20, 30% 30, 40% 40, 50% 50, 60% 60, 70% 70, 80% 80, 90% 90. |
Voice samples
New to Batocera v32, a recent update to libretro: O2EM added sample support for emulating the voice synthesis module. Download the samples from O2EM's homepage (hover over “Misc” near the top of the page) and extract them into /userdata/bios/voice. Sid the Spellbinder requires its own pack, but if you're not intending on playing that game they're not required.
To confirm they are loaded correctly, K.C.'s Krazy Chase! plays a voice sample almost immediately after starting a game.
