So these emulators are very special to me... the DS is a unique handheld that is perfectly suited for the systems with various controller options. The consoles and computers I had as a kid (young teen) are pretty much the Intellivision followed by ColecoVision and then an 800XL (the only other pre-PC system I had was an Atari ST), so I can tell you that I truly appreciate all the hard work which has gone in to these emulators. It's the attention to detail and usability which is the best feature here...

I finally got some time to go back to my Nintellivision emulator to see how easily cheats could be added.

Turns out it's not too bad... took an hour just to get my head wrapped back around the 8-bit and 16-bit memory spaces here.

As a proof-of-concept, I was able to take the 'Starting Weapon' cheat for Treasure of Tarmin and poke in value 33h and you can see the (proper) result of a Platinum Crossbow at the very start of a game.

I plan on building out a full cheat-menu for a number of games which you can enable/disable various cheats using touch-screen check-boxes or similar easy toggle method. By default, all cheats are disabled but the ones you enable can be saved into your configuration on a per-game basis so they come back up as you desire.

I'm a little worried about the time-sink on this... it's cool and all, but I wonder if anyone would actually use such a feature!

(ignore the lower-touch-screen debugger graphic... that's just for me to play with... the normal overlay would show here of course)

Nice to see some Nintellivision news. Speeking for myself, I will not use such a feature, I do not like cheats. I prefer the way the games are meant to be played.
Yeah, I'm the same way! However, 'cheat' is a strong word which I probably should have avoided... many of these are more like hacks which are slightly different. For example, there is an easy way to disable the background color changing in Astrosmash so it's always black. Some of the color choices are really hard on the eyes with regards to the color of falling rocks - and the black background always looks nice with solid contrast. So is that a "cheat" - not really... more of a quality of life improvement for some.

Still... I'm running out of things to improve so this was next on the list :)

New release: https://github.com/wavemotion-dave/NINTV-DS

V3.6 : 24-May-2022 by wavemotion-dave
  • Added cheat support. Place NINTV-DS.cht into /data directory. See 'extras' folder.
And now announcing a very special release that literally nobody was waiting for!! I've added most of the cheats (with permission) kindly provided by Michael Hayes at http://www.midnightblueinternational.com/romhacks.php - he's done a great job uncovering a number of cool tweaks, hacks and cheats for about 30 of the most popular games.

All cheats are disabled by default - and I decided you can't enable/save cheats on a per-game basis. So you'll have to re-enable them when you want to play around... this way we avoid anyone accidentally leaving a cheat/hack enabled.
