lr-freeintv is a libretro emulation core for the Mattel Intellivision designed to be compatible with joypads from the SNES era forward even if they originally required a number pad.


lr-freeintv requires two Intellivision BIOS files to be placed in the libretro 'system' folder:

Function Filename* MD5 Hash
Executive ROM exec.bin 62e761035cb657903761800f4437b8af
Graphics ROM grom.bin 0cd5946c6473e42e8e4c2137785e427f
  • BIOS filenames are case-sensitive

Entertainment Computer System and Intellivoice

lr-freeintv does not currently support Entertainment Computer System (ECS) and Intellivoice functionality. Contributions to the source are welcome!

Controller overlays

Mattel Intellivision games were often meant to be played with game-specific cards overlaid on the numeric keypad. These overlays convey information which can be very useful in gameplay. Images of a limited selection of Intellivision titles are available at:


  • Mini-Keypad - Allows the user to view and select keys from a small Intellivision pad in the lower corner of the display.
  • Controller Swap - Some Intellivision games expect the left controller to be player one, others expect the right controller. This isn't a problem if you have two controllers (and don't mind juggling them) but users with only one controller or using a portable setup would be effectively locked out of some games. Controller Swap swaps the two controller interfaces so that the player does not have to physically swap controllers.

lr-freeintv utilises Retroarch controller configurations. Add custom retroarch controls to the retroarch.cfg file in /opt/retropie/configs/intellivision/retroarch.cfg

jzIntv requires at least the first two Intellivision BIOS files listed below to be placed in the libretro 'system' folder:

Function Filename* MD5 Hash
Executive ROM exec.bin 62e761035cb657903761800f4437b8af
Graphics ROM - 213 predefined character images and some EXEC routines; Tutorvision variant grom.bin 0cd5946c6473e42e8e4c2137785e427f
Entertainment Computer System (ECS) ROM - additional EXEC routines, the BASIC programming interpreter, and graphics of musical notes ECS.BIN 2e72a9a2b897d330a35c8b07a6146c52
Intellivoice RESROM - resident ROM containing common speech words and phrases as well as program instructions IVOICE.BIN d5530f74681ec6e0f282dab42e6b1c5f
Keyboard Component EXEC ROM - BIOS for the Keyboard Component peripheral; PicSe (picture sequencer) routines for multimedia software ? ?
  • BIOS filenames are case-sensitive


By default, jzIntv maps the first (left) analog stick to the left controller's disc input. In addition, the first 9 buttons are mapped to the 3 action buttons as follows:

Buttons 0, 3, 6:  Top action buttons, left controller
Buttons 1, 4, 7:  Lower left action button, left controller
Buttons 2, 5, 8:  Lower left action button, left controller

jzIntv maps the first joystick's first hat's 8 directions to the numeric keypad on the right controller, making the hat usable in games such as Night Stalker and TRON Deadly Discs. [Source]

It is possible to remap these using a keyboard hack file. Instructions on creating these can be found HERE. Keys 0, Clear and Enter on the numeric keypad are not mapped by default so a keyboard hack file would be required to this.

Keyboard Controls

Function/Special keys, all maps:
    F1              Quit

Memory Map Config Files:

If a rom does not load leaving you with a black screen (and the files dump.cpu and dump.mem in your home folder upon exit), then you need a memory map config file. This is likely to be the case for titles from Atarisoft, Imagic or INTV Corp.

First determine which config file your rom requires from this spreadsheet.

Next download the config file from here and rename it the same as the your rom.

For example, you are trying to get to work. From the spreadsheet, you see that it takes memory map #7 so download 7.cfg and rename it atlantis.cfg. Place it in your roms folder and your rom should now work.

Full details about using memory map config files can be found here.
