Channel F

The Fairchild Channel F (a.k.a. Video Entertainment System) is a first-generation home videogame console developed by Fairchild. It was released in November 1976 and retailed for $169.95 USD ($819 in 2021). It is the first console to use a microprocessor.

The “F” in Channel F stands for “Fun”! :-D

This system scrapes metadata for the “channelf” group and loads the channelf set from the currently selected theme, if available.

These two BIOS files are required:

MD5 checksum Share file path Description
ac9804d4c0e9d07e33472e3726ed15c3 bios/sl31253.bin Channel F BIOS (PSU 1)
da98f4bb3242ab80d76629021bb27585 bios/sl31254.bin Channel F BIOS (PSU 2)

The Channel F II BIOS is optional; games are compatible with either BIOS. If included, the Channel F II BIOS will be used instead of the equivalent Channel F BIOS.

MD5 checksum Share file path Description

Place your Channel-F ROMs in /userdata/roms/channelf.

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] + South button (B SNES) 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: channelf.videomode, channelf.ratio, channelf.smooth, channelf.shaders, channelf.pixel_perfect, channelf.decoration, channelf.game_translation

ES setting name batocera.conf_key Description ⇒ ES option key_value
Settings that apply to all cores of this emulator
GRAPHICS BACKEND channelf.gfxbackend Choose your graphics rendering
⇒ OpenGL opengl, Vulkan vulkan.
AUDIO LATENCY channelf.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 channelf.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: FreeChaF

FreeChaF is a libretro core for the Fairchild Channel F.

libretro: FreeChaF configuration

Access to the console buttons is provided via an overlay. Pressing 'start' on either controller will display the console buttons. You can select a button by moving left and right and press the button with any of the face buttons (A, B, X, Y). Pressing 'start' a second time will hide the overlay.

Here are the default Channel-F's controls shown on a Batocera Retropad:

FreeChaF Function Retropad
Forward D-Pad Up, Left-Analog Up
Backward D-Pad Down, Left-Analog Down
Rotate Left Y, L, Right-Analog Left
Rotate Right A, R, Right-Analog Right
Pull Up X, Right-Analog Up
Push Down B, Right-Analog Down
Show/Hide Console Overlay Start
Controller Swap Select
  • Console Overlay: Allows the user to view and select console buttons.
  • Controller Swap: Controller Swap swaps the player 1 and player 2 controllers.
