On the Mac from update 13.0.5 (v2031616): the opening movie, the title, the first launch's DLC unlocks and Challenges board, the main menu, rulesets, stage and fighter select, 2-player battles (Frigate Orpheon, Big Blue, Great Bay, Find Mii, Prism Tower, Kongo Jungle 64) at 60 fps with about 2.7 ms of GPU per frame and 2 GB resident (1.2 GB of Metal allocations), quitting to the results and a second battle whose fighters' NROs the game loaded again; no red line in battle.
- Profile: modules main subsdk0 sdk (Catherine: Full Body's sdk and movie builds), the 5 GB guest layout, shader groups for data.arc's shader databases, effects and UI layouts, 35,012 shaders.
- patches.py: the engine's allocator (main+0x37c9a20, a static constructor) reserves 62 GB of address space with AllocateAddressRegion and aborted at main+0x37c9bd0. Booted once with a 64 GB alias region it commits from the region's start up (1.73 GB at the title, up to 2.5 GB in a battle) and keeps its page tables in the top 14 MB; all 11 instructions derived from the size are cut to a 4 GB region.
- sdk_patches.py: this SDK 8.2.1 sdk build (5fd4f531, Catherine's too) has the 1 GB AddressRegionManager node area and the 1 GB alignment of large regions (DRAGON QUEST XI S's SDK 7.3.2 layout at sdk+0x336b40 / +0x336d5c); both cut, so the region starts 64 MB into the 4.375 GB alias region.
- NVN: nvnSetExternalDebuggerEnabledNVX, fetched with nvnDeviceGetProcAddress(NULL, …) before the device and called unchecked (pc=0 from main+0x37fe92c), is a no-op in names.txt / hle_nvn.c, as docs/agents/03 already described.
- iOS NRO embedding (the part d979c34 left out): gen_embed.py packs the NROs nro.tsv lists into three sections (__TEXT,__dm_nro_x0, __DM_NRO_W,__img, __TEXT,__dm_nro_x1) with a table of their pieces (__DATA,__dm_nro_tab), since a Mach-O file has at most 255 sections and three per NRO would take 294; loader.c map_image maps an NRO from there (nro_pieces); build_ipa.sh puts nro.tsv beside the rewriter tables. The 98 NROs add 157 MB of code and 51 MB of data to the executable.
- shader_split.py reads data.arc through smash_arc.py (smash_arc_jobs / smash_arc_shaders: each current file scanned, labelled /data.arc/<format>#<hash40>); smash_arc.files(regions=True) gives every region's data of a regional file, without which 128 effect shaders were missing (34,884 of 35,012).
- Docs: README (games table, a Mac picture of Great Bay), AGENTS.md (50 → 51), docs/development.md (game notes, the NRO paragraph, nro_collect.py), docs/agents/01 (data.arc) and 03 (the 4 GB cut and its measurements, iOS NRO embedding).
Checked: the NSP script packs it from the NSPs alone, for the Mac and for iOS; tool tests (41), host unit tests and the NRO loader test pass. Played on an iPhone with this port's build from before it moved onto d979c34's NRO loader; the merged build was checked on the Mac (battles, an NRO loaded again) and builds for iOS.
