Features

  • Three machines - Odyssey 2 (NTSC), Videopac G7000 (PAL) and Videopac+ G7400 (PAL, with its text layer)
  • .bin, .rom and .o2 cartridges, including the 4-in-1, Rally and KTAA mappers
  • Controllers window showing the console's membrane keyboard and both joysticks, remappable to keyboard and gamepad
  • The Voice speech module, switched on in Preferences
  • Debugger with Prompt, CPU & RAM, Disassembly, Video, EF9340, Sound & I/O, Breakpoints, Cart and FujiNet tabs
  • FujiNet CONFIG runs on a built-in stand-in BIOS, so nothing is needed to start
  • 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 about 120 bytes. Games need the real BIOS, and every machine needs the 8244's character set to show text.

FileWhat it isCRC32Needed
o2bios.rom Odyssey 2 / Videopac G7000 BIOS (1 KB) 8016A315 Optional
g7400.bin Videopac+ G7400 BIOS (1 KB) E20A9F41 Optional
charset_i8244.bin 8244/8245 character set (without it text is blank) (0 KB) B46A3F31 Optional
charset_ef9340_1.rom EF9340 character set (G7400) (2 KB) 8DE85988 Optional
sp0256b-019.bin The Voice - SP0256 ROM (2 KB) 4BB43724 Optional
spr128-003.bin The Voice - speech ROM (16 KB) 509367B5 Optional
spr128-004.bin The Voice - Sid the Spellbinder speech ROM (16 KB) E79DFB75 Optional

How to add them: Machine ▸ Import BIOS… takes a single file, a zip (MAME's videopac.zip, i8244.zip, videopacp.zip or ef9340_1.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 Odyssey 2's ROMs; MAME calls this set videopac.
