Over on Twitter, Beta64 revealed that the Nintendo DS Lite has an unused video output feature that allows you to play DS games on your TV, or it would if it wasn't disabled. In other words, it's technically a cut feature, but it's one Nintendo never talked about and nobody knew about.
I just learned today that the DS Lite has an unused "video output" feature disabled on boot that allows you to play DS games on your TV, and the hacking team Lost Nintendo History managed to restore the feature. So freaking cool!https://t.co/B3Kxr7yB5I pic.twitter.com/4FxQLDx0XL— Andrew (Beta64) (@Beta64Official) February 22, 2021
As for the discovery itself, it was actually made by Lost Nintendo History, who revealed they made the discovery late last year and have since been able to restore it and make it usable for others.
"During late 2020, we discovered that the Nintendo DS Lite had a leftover feature in its SoC allowing it to easily have cheap hardware video output," writes Lost Nintendo History of the discovery. "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. This mod is especially useful to revive consoles with only the lower screen, being able to watch the upper screen on your TV. Or to create a GBA Macro with additional TV Output."
