I was just thinking, what if we could be able to decrypt 3DS ROMs without needing a 3DS console or xorpads to do so?

Well, I was actually wondering, how can I be able to find keyslot 0x2C for KeyX? This keyslot is known to be the main NCCH key for decrypting 3DS ROMs since the very beginning, we could might as well call it a "common key". As it's documented here: https://3dbrew.org/wiki/AES_Registers

As far as I'm aware, if we don't have some program that can extract all the decryption keys on the 3DS, how in the world would 3DS emulation be able to proceed?

We know how the algorithm works, since the key generator for the 3DS was made, but how can I extract the 0x2C KeyX from the 3DS? And no, I'm not talking about the 0x25 KeyX that was made in version 7.x. I'm talking about the original KeyX slot, which is used in much older 3DS games.

    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

    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

  • 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

    @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.

    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.
