Features

  • Four machines - Channel F and System II (NTSC), Saba Videoplay and Videoplay 2 / Luxor (PAL)
  • .bin and .chf Videocarts, including Maze and Hangman (2102 RAM), Chess and the multicarts
  • Controllers window with both hand controllers' four axes - tilt, twist, pull and push - remappable to keyboard and gamepad
  • Debugger with Prompt, CPU & RAM, Disassembly, Video, Sound & I/O, Breakpoints, Cart and FujiNet tabs; the Video tab shows the whole 128 x 64 VRAM, each row's palette and every write
  • FujiNet CONFIG runs on a built-in stand-in BIOS, so nothing is needed to start
  • Built-in Help
  • FujiNet web UI in your browser, or switch to an external FujiNet

BIOS ROMs

Optional

CONFIG and FujiNet apps run on a built-in stand-in BIOS of under 200 bytes. Videocarts need the console's BIOS.

FileWhat it isCRC32Needed
sl31253.rom Channel F BIOS (first half) (1 KB) 04694ED9 Optional
sl90025.rom Channel F System II / Luxor BIOS (first half) (1 KB) 015C1E38 Optional
sl31254.rom Channel F BIOS (second half; every machine) (1 KB) 9C047BA3 Optional

How to add them: Machine ▸ Import BIOS… takes a single file, a zip (MAME's channelf.zip) or a folder, and recognises each dump by size and CRC.

There is no public download we can link to. Use a dump of your own Channel F's ROMs; MAME calls this set channelf.
