It seems like there could be vulnerabilities in Nintendo's ARM7 IPC code. Has anyone investigated this?

Even when booting a cart, SCFG is locked. The only thing that has unlocked SCFG is Launcher, hence RocketLauncher exploiting the launcher. Before booting a game (cart or otherwise), Launcher locks SCFG.

Yeah you have to exploit Launcher or the stage2 bootloader on NAND (equivalent to FIRM partitions of 3DS....sorta). No official software besides Launcher runs with unlocked SCFG. Not even a few of the system Dev apps had it. twlNmenu has a few other things unlocked (a dev app that has both slot-1 and nand enabled), but even that app doesn't have unlocked SCFG. That app only is signed for dev hardware anyways so you can't use that one on retail hardware.

    Usually when such a big title leaks the Temp will be the first to report about it (going off of historical reports here, Pokemon SV being the latest one I can recall seeing pop up here)

    I want a 120hz 4k tv but crazy how more expensive the 120hz over the 60hz are. Or even more crazy is the price of 8k's.
  • K3Nv2 @ K3Nv2:
    No real point since movies are 30fps
  • BigOnYa @ BigOnYa:
    Not a big movie buff, more of a gamer tbh. And Series X is 120hz 8k ready, but yea only 120hz 4k games out right now, but thinking of in the future.
  • K3Nv2 @ K3Nv2:
    Mostly why you never see TV manufacturers going post 60hz
  • BigOnYa @ BigOnYa:

    I got my Dad a firestick for Xmas and showed him those 3rd party sites on Kodi, he loves it, all he watches anymore. He said he has got 3 letters from AT&T already about pirating, but he says f them, let them shut my internet off (He wants out of his AT&T contract anyways)
  • K3Nv2 @ K3Nv2:
    That's where stremio comes to play never got a letter about it
  • BigOnYa @ BigOnYa:
    I just use a VPN, even give him my login and password so can use it also, and he refuses, he's funny.
  • BigOnYa @ BigOnYa:
    I had to find and get him an old style flip phone even without text, cause thats what he wanted. No text, no internet, only phone calls. Old, old school.

    @BigOnYa, Lol I bought a new USB card reader thing on AliExpress last month for I think like 87 cents. Free shipping from China... It arrived it works and honestly I don't understand how it was so cheap.
