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.
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.
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.
