What is it?

• An Intellivision emulator for the DS/DSi/XL/LL and other sundry compatible handheld devices.

Who made it?

• A highly talented individual that goes by the name Wavemotion. 

Where do I download the emulator?

• Visit the official Gibhub page here: https://github.com/wavemotion-dave/NINTV-DS

Where can I discuss the Nintellivision with a group and Wavemotion directly?

• Head over to the official Atari Age discussion thread here: https://forums.atariage.com/topic/362563-nintellivision-ninty-ds-official-release-and-discussion-thread/

What can it do?

• Load and run virtually any Intellivision game on the planet. On the DSi or above (with the 2X CPU), all games run at full speed, full framerate and with the best sound quality. On the older DS-Lite/Phat, most games run full speed with just the occasional slowdown and/or reduction in sound quality (most evident on Intellivoice games).
• Custom Overlay Support. More than 70 high-quality custom overlays have been developed by various users of the emulator over the past two years.
• Manual/Instruction Support - with many of the Intellivision games being a bit more complex than other games of the era, the manuals are required reading.
• Save Sate support (3 save slots per game).
• High Scores for up to 10 scores per game with various sorting options.
• Cheat / Hack support using NINTV-DS.cht (see 'extras' folder and place in /data directory)
• Numerous button / controller mapping options. Dual-Controller support (run and shoot at the same time in games like Deadly Disks or AD&D Cloudy Mountain).
• Full Intellivoice support to let you hear all the games that love to talk.
• JLP support for accelerated functions (multiply/divide), extra RAM and flash memory. 
• ECS support with keyboard including sound-enhanced games like Space Patrol which take advantage of the extra PSG.
• ROMs load up to 1MB (1024K) in size - that's more than twice the size of the currently largest available game/demo (Bad Apple).

How do I install and run the emulator?

• To run this on your DS or DSi (or 2DS/3DS) requires that you have the ability to launch homebrews. For the older DS units, this is usually accomplished via a FlashCart such as the R4 or one of the many clones. These tend to run about US$25. If you have a DSi or above, you can soft-mod your unit and run something like Twilight Menu++ or Unlaunch which will run homebrew software on the DS. The DSi has a convenient SD card slot on the side that saw very little use back in the day but is a great way to enjoy homebrews. See https://dsi.cfw.guide/ to get started on how to soft-mod your unit.
• You can run an R4 (or similar) flashcart on the DSi or 2DS/3DS to run the emulator but these cards generally run in 'compatibility' mode meaning they will not unleash the 2X CPU and 4X Memory of the DSi or above. That's okay - but realize you will not get the full throughput of your device.

I don't have a DS/DSi/XL/LL - what would you recommend?

• I always recommend the DSi XL (USA) or LL (same unit but Japanese). These are a bit larger and have a slower refresh on the LCD which more closely mimics the phosphor fade of a real TV. The XL/LL units are built like tanks - they can take a beating and deliver a smooth playing experience. Like any DSi, they will also have the SD card slot which is the easiest way to soft-mod your device for playing homebrew games. All seven of my emulators will run on just about any DS hardware - but I always run them on a DSi XL or LL (I have several units as you might imagine).  These units will set you back at least $75 - one trick to reduce the cost is to try and find a 'broken' one - something that has perhaps the flash cart slot broken. Those are fine since you won't need to use the flash cart to load normal games - you're really interested in the SD card slot on the side (which was underutilized for almost any real purpose when the machine was in the marketplace - fortunately homebrewers can use it).

Why did you do this?

• I love the Intellivision and the DS is well-suited to handle the overlay via the touch-screen. I was one of the disappointed buyers of Intellivision Lives on the DS which had a number of glitches - missing sounds, missing row of graphic tiles at the bottom for some games (my favorite game - Treasure of Tarmin aka Minotaur was virtually unplayable) and a number of collision detection issues left me feeling like it was a missed opportunity. Nintellivision seeks to correct that with a mostly ground-up (parts borrowed and improved from the old Bliss core) development to take advantage of the DS capabilities and expand it to play modern homebrews utilizing the JLP features. When you compare Nintellivision to Intellivision Lives, I think you'll find Nintellivision plays more like the real thing. After trying both... Intellivision Lives left me... rather flat.
