Intellivision core

This is a port of the MiSTer Intellivision core to the Turbo Chameleon 64 cartridge

This is an experimental core, and while I do my utmost to make sure it works for everyone and will try to help solve any problems that arise, you run this core entirely at your own risk.

If you’d like to show your appreciation for this core, or motivate me to work on this and other cores in future, donations are welcome at or Anyone donating £20 or more via PayPal or sponsoring on Patreon at the second tier will be thanked by name in a “Core Supporters” shout-out page in subsequent releases.

Please note: it’s vitally important that you download the correct version of the core for your Chameleon.

Intellivision for Chameleon V1 hardware: If you have a single mini-DIN socket on the left hand side of your Chameleon, to which a breakout cable attaches for the keyboard and mouse, then you have V1 hardware and need this version:

Intellivision for Chameleon V2 hardware:  If you have three mini-DIN sockets on the left-hand side, with the keyboard and mouse plugging in directly, you have V2 hardware, and need this version:

Currently supported:

  • Cartridge ROMs
  • ECS ROM / keyboard emulation
  • Intellivoice support
  • C64 keyboard / joystick
  • CDTV joypad


The core requires a ROM file in the root of the SD card, called INTV.ROM. An example ROM file can be found at


If ECS mode is enabled, then the PS/2 and C64 keyboards are usable directly. When ECS is disabled, the keyboard emulates the Intellivision gamepad.

This core is ported from the MiSTer Intellivision core, written by Grabulosaure and Kitrinx.

The Turbo Chameleon 64 port wraps the MiST port core in a compatibility layer (DeMiSTify, by Alastair M. Robinson), and makes very few material changes to the core itself.
