Nintellivision, also known as NINTV-DS, is an Intellivision console emulator running on the DS/DSi.


  • All known games run at full speed on a DSi or above.
  • Many games run very close to full speed on the older DS-LITE and DS-PHAT hardware but you can play with config settings to get the most out of these games.
  • Custom Overlay Support. See the extras folder for details.
  • Manual/Instruction Support. See the extras folder for an example.
  • Save Sate support (3 save slots per game).
  • High Scores for up to 10 scores pre game with various sorting options.
  • Tons of button/controller mapping options. Dual-Controller support (run and shoot at the same time).
  • JLP support for accelerated functions, extra RAM and flash memory. When loading a game, use the X button to load and force JLP support ON if not auto-detected.


Note: You will need to prepare the BIOS files (grom.bin, exec.bin) in order to use. Optional is ivoice.bin for Intellivoice games.

Place the nds file on your flashcart or SD card which you can launch.

Put the BIOS files in the same directory as your ROM files (can be changed in Global Options).

User guide

When you load the emulator, select LOAD to select a cartridge/game to play. The emulator supports two types of files, raw binary files (BIN or INT) and intellicart ROM files (where the .ROM contains the loading information, popular among newer homebrew games).

Once loaded, the configuration (or default settings) is loaded with the game. You can pick your overlay, and tweak key mappings and other settings in configuration.


Please see to the enclosed tutorial (in the extras folder) of how to create custom overlay.

You can find a number of custom overlays and manuals from the release thread:

To use overlay, rename .txt to .ovl for your game, then copy it along with the .png file to your card or sd card. Note that the file names should be the same as your rom name and they can be placed together with the rom (can change to /roms/intv/ovl/ or /roms/ovl/ via Global Option).

Manuals can also be placed with your rom files (can change to /roms/intv/man/ or /roms/man/ from the Global Option).

New palette can be created using text file and store it as /data/NINTV-DS.PAL (see example).

Once you loaded the game, go to CONFIG to change overlay settings and option for game manual is located in MENU.

Key mappings

In configuration you can map 6 of the DS keys as well as set some other options. Of note here is the Dual Action controller which has the Disc/Buttons on one controller and the Keypad mapped to the other controller.

The Intellivision could not distinguish keypress buttons when the disc was pressed - but this lets you get around that (in short, it lets you do things like move and shoot at the same in AD&D Cloudy Mountain).

To gain more speed, you can tweak the audio settings (higher numbers are lower quality and faster speed). You can also try the Aggressive Frameskip option which is a bit dangerous in that it can cause sprite collisions to not be detected - so it works for some games and not others. But if you're desperate for more speed, give it a try.

Many games run close to full speed on DS-LITE and DS-PHAT hardware, but you can play with config settings to get the most out of these games (even if you have to disable sound to gain the speed).

Also tested on emulator iDeaS and melonDS.
