Lost Nintendo History is a group of Nintendo enthusiasts and skilled hackers and engineers aiming to uncover and restore the secrets of Nintendo´s software and hardware that has been lost to time.
They discovered that the Nintendo DS Lite had a leftover feature in its SoC allowing it to easily have hardware video output.
With a little circuitry and some software hacks, they were able to restore it and make it usable for anyone.
During late 2020, we discovered that the Nintendo DS Lite had a leftover feature in its SoC allowing it to easily have hardware video output.
With a little circuitry and some software hacks, we were able to restore it and make it usable for anyone!
No FPGA’s, no bulky or cumbersome hardware.

Software
The retail firmware of the Nintendo DS Lite (not the BIOS) disables this specific feature early in the boot process.
To reenable it, we use a custom firmware like flashme, which is very easy to install and is required only once.
Despite that, we are working on an even simpler solution to make it available to as many people as possible, our own custom firmware.

Hardware
This feature is only found on the Nintendo DS Lite. Nintendo DS Phat does not contain this feature nor does the Nintendo DSi.
It is important to remark that this is not the same hardware found on Devkits or other special units.
This hardware feature is present in virtually every single Nintendo DS Lite out there.
The reason why it was left there is unknown, but as said before, it is not related to development units, those use a different video capture hardware.
Maybe Nintendo imagined the Nintendo Switch as early as 2006?

We only need a few extra hardware components to make this video signal usable.
You will be able to download the schematics and gerber files for our open hardware circuit board from the repository.
NOTE: Currently working on revision 1.2 to fix some minor issues.
The final, production-ready board contains a DAC (Digital to Analogue Converter) which turns the 10 bits digital signal at 16.7 MHz provided by the DS Lite into a proper analogue signal.
This signal then goes through an amplifier and it’s ready to be delivered to your nearest TV trough composite video.

    @Julie_Pilgrim "very bright" is essentially pure white

    pure white doesn't show up all that much it's mainly when looking at a bright sky

  • The Real Jdbye @ The Real Jdbye:
    and if the clouds in the sky have slightly less definition to them because i turned on the contrast enhancer who cares

    that's not important

    i can't tell the difference

    but i can certainly tell the difference with black crush if i'm watching a scifi movie and i can't see wtf is going on

    Human vision is logarithmic, it's not linear. And nits doesn't tell the whole story of perceived brightness. OLED'S look brighter then LCD's even when both are set to the same nit values because of the higher contrast ratio on OLED's

    OLED's have a 3D look

    Charging port is more likely to fry up or battery fail before the display tbh lol

    "And nits doesn't tell the whole story of perceived brightness" it's not about perceived brightness it's about all HDR content in TV and movies being mastered for 1000 nits so it doesn't look right with anything lower, it's also about dynamic range

    "OLED's have a 3D look" no they don't lol

  • SG854 @ SG854:
    As an owner of a OLED and you saying that you never seen an OLED I think I know what I'm talking about lol. I'm not talking about 3D as in 3D glasses. I'm talking about depth and pop in the picture

    I mean to be fair og vitas are still kicking and not many have suffered from pixel bleed and they're going on nearly 10 years
    Gift
  • SG854 @ SG854:
    OLED's can get away with a lower peak brightness and still provide punchy HDR because of their contrast ratio. Like I said human vision is logarithmic. The higher the peak brightness the diminishing returns in perceived brightness.

    Just get 5 years enjoyment out of it until Nintendy releases something and everyone forgets about switch games lol

  • SG854 @ SG854:
    @The Real Jdbye Oleds hit around 750 nits nowadays. The difference between a 1000 nit and a 750 nit isn't huge. It's only about a 4% increase in perceived brightness. Not huge at all. You'll need at least 2000 nit displays to notice a bigger difference.

  • SG854 @ SG854:
    Read this thread it explains it. 1000 nits is not a huge jump from 750 the LG OLEDs can hit. As I said human vision is non linear.
