- The crash about 6 minutes into the prologue battle (null write at
main+0x9a4664) was the alias region running out of address space, not
memory: Unity's low-level virtual allocator got no region from
AllocateAddressRegion and returned 0. The SDK's AddressRegionManager
keeps the first 1 GB of the alias region as its node area and aligns
each region by size; after StandardAllocator's 3.14 GB block only about
1.2 GB was left for Unity, and it was full and fragmented.
- patch_nso.py: a host-only cut for Engage's sdk build (56ec2474…)
shrinks the node area from 0x3fe00000 to 0x3e00000 (62 MB, about 1.35
million nodes). Both constructor movs change together.
- A 12-minute scripted run now plays through the battle without a crash;
reserved address space levels off at 4.17 of 5.31 GB.
- hle_svc.c: the alias-mapped total counts pages with a bitmap, so maps
of already-mapped pages and oversized unmaps no longer skew it (it went
negative). Engage really maps about 1.5 GB, not 0.5 GB.
- Docs: bring-up catalogue entry with the measuring recipe, profile
memory notes, README Engage row. Mario regression t64 clean; the iOS
project compiles.
