tbh I have no idea if nintendo will try to take this down, but I'm sure they *want* to, for the same reason they're going after an accessory maker for showing the physical design of the switch prior to announcement
the apple chips have pretty comparably sized GPU and CPU areas, but there's still no absolute honker GPU like you'd get in a console chip (left is Xbox Series X, right is M1 Ultra)
i love those types of videos that only make sense in a context where the subject is an unreleased product, so we get thrilled at any exclusive insight that will, by the time it’s widely available, be nothing so exciting
Even if they do have pointer auth, it's not going to impact *much* in the overall security model, especially for the attacks I have in mind. All the switch 1 games, which the switch 2 is compatible with, have been built without PAC.
i dont really know anything about the original switch so idk what that model looks like - but in any case, you still gotta deal with pac again when you break out of el0?
It appears like backwards compatibility is using some kind of emulation (probably container style tech with some instruction translation). In part because the GPU is quite different
Given the reported issues for some games it seems like it's not just the GPU which is different? (unless some of these games offload compute to the GPU in weird ways)
Can you give an example? I don't see any reason why they'd emulate an ARM core on a compatible ARM core, especially given perf/battery-life is a huge priority for them

Maybe the runtime use PAC?
