basically, memchunkhax2 and ironfall. not even browserhax or menuhax were patched. https://www.3dbrew.org/wiki/APT:IsTitleAllowed https://www.3dbrew.org/wiki/10.4.0-29
well there's a video of someone trying memchunkhax2 and it said exploit failed or something like that
That's not really confirmation until they adjust for the new kernel version. libkhax -steveice branch shows unsupported kernel.
"memchunkhax2 was fixed by reading the MemoryBlockHeader next pointer before it is mapped to userland."
