- Audio: run the sdk's own audio renderer on the CPU in manual mode (hle_audren.c),
feed its DeviceSink output to the AudioOut sink; catch-up render on back-to-back
updates fixes the ApplyLightLimiterEffect crash at the title screen
- Button icons: make_ext_font.py generates a stand-in Nintendo extension font
(A/B/X/Y, L/R/ZL/ZR/SL/SR, +/-, D-pad, stick arrows); served as shared font type 5;
the iOS bundle now carries both shared fonts
- Fountain panels: Metal 4 does not order copies inside one encoder; add barriers
when ranges overlap, so the GPU wave simulation no longer reads a stale uniform
- Zero-fill new colour textures; scissored zero clears; uniform-update snapshots
- Docs: graphics ordering, audio, diagnostics, intermittent-glitch method
- dm/ios: lean app shell (main.m boot/env/log, front_ios.m front.h + 16:9 Metal view,
DmGamepad.m touch gamepad in Nintendo positions + GameController), xcodegen project,
tools/build_ipa.sh (embedded game code, iOS shader libraries, RomFS in the bundle)
- Guest address space back to 5 GB (heap 1.625 GB; the game asks for 1.47 GB)
- README / agent guide: iOS build steps and address-space sizing
- dmsh_build.py: vertex shaders whose inputs are only used as integer bit casts are
re-translated with uint inputs (529 shaders); bone indices were converted to floats and
every character was stretched off screen
- Host: Metal vertex formats follow the shader input type (signedness swap, 32-bit float
reinterpretation), mismatches reported
- LINEAR_RENDER_TARGET textures in CPU-visible pools are zero-copy too (sky colour ramps)
- Pass dump lists all vertex attributes; docs and README updated
- patch_nso.py: Mario main cut gives every resource heap +16 KB; Model/NpcCommonerA.bfres
came up 0x70 bytes short of its size-table budget while loading Course900
- dmsh_build.py: compute instructions start at code area +0x100, not +0x30; the misaligned
decode turned 12 particle / post-effect compute shaders into endless loops (GPU hang)
- Linear textures in CPU-visible pools are built on the pool buffer, so the CPU-rasterized
glyph cache reaches the GPU (menu and dialogue text)
- Host command-memory segments grow on demand; RGB10A2SN vertex format; instanced DrawArrays
- DM_PROBE: thread IDs, register-relative dumps, hit filters, ExpHeap walker
- dm/tools/ghidra/Decompile.java; agent guides and README updated
- DM_KEYS scripted controller input ("seconds:button[+button][~hold]")
- NVN virtual memory pools aliased onto their physical pool when every
MapVirtual request shares one base (Mario's 128 MB pool); previously
MapVirtual failed and the game treated the pool as unusable
- DM_PROBE ported from d2r-mobile (host/probe.c): brk probes with
register / backtrace output, plus DM_PROBE_X2 object dumps; used
because lldb launches now wait on a macOS authorization prompt
- diagnostics: DM_NVN_VLOG (pools, MapVirtual), DM_NVN_CBLOG (command
memory grants and callbacks), DM_NVN_ALLOCPROF
- docs: new failure patterns and the probe recipe
Open: starting a new game crashes while loading the opening course
(model resource heap overflow for NpcCommonerA.bfres).
Shaders
- shader_split.py (new): scan RomFS and main for every BNSH and agl BAHS
container (bfsha, particle effects, layouts, agl/gsys packs, main):
12,811 shaders, map + compute facts from the control section
- key = sha256(control + code): many shaders share a control section
- NVN 55 binding layout: bound textures at 0x20 + 8*slot, images 0x120
- bindless textures read from uniform buffers (tex_ubo / samp_ubo)
- GL depth mode: translator remaps z' = z/2 + w/2 in vertex shaders
- compute code areas carry a 0x30 header (magic 0x12345679)
Replay
- 8-bit index buffers widened to 16-bit
- texture swizzle through Metal swizzled views
- non-packaged textures shared by storage (fixes a ~13 MB/frame leak
from transient render targets rebuilt every frame)
- view_t packed to 16 bytes (SDK 16 NVNtextureView; fixes a stack smash)
- TBDR optimizations off by default until they know bindless readers
Host
- alias region 2.875 GB for the 1.75 GB VirtualAddressMemory reservation
- ideal core -2 resolves to the process default core
- shared font served with a BFTTF "decoded" header
- crash reports scan the stack and dump the popped frame
